Abstract

A linear accelerator based source of coherent radiation, FLASH (Free-electron LASer in Hamburg) provides ultra-intense femtosecond radiation pulses at wavelengths from the extreme ultraviolet (XUV; λ<100nm) to the soft X-ray (SXR; λ<30nm) spectral regions. 25-fs pulses of 32-nm FLASH radiation were used to determine the ablation parameters of PMMA - poly (methyl methacrylate). Under these irradiation conditions the attenuation length and ablation threshold were found to be (56.9±7.5) nm and ∼2 mJ∙cm-2, respectively. For a second wavelength of 21.7 nm, the PMMA ablation was utilized to image the transverse intensity distribution within the focused beam at μm resolution by a method developed here.

1. Introduction

PMMA ablation has been extensively investigated with conventional UV-Vis-IR lasers (see for example [1,2]). PMMA is also widely used in electron-beam, EUV, and x-ray lithography as a resist. Therefore its radiation-chemical and radiation-physical properties have been extensively studied and nowadays they are well understood over a wide range of irradiation conditions. PMMA erosion induced by high-energy photons (often also called direct photo-induced PMMA etching) in vacuum has already been investigated with synchrotron radiation [3,4] and with incoherent XUV/X-ray radiation from plasma-based sources [5,6]. Earlier studies [7–9] in the XUV laser-induced ablation of PMMA showed that the process is very clean. Furthermore, the PMMA material removal is governed by non-thermal processes and therefore restricted to the irradiation spot and its closest vicinity. These properties are the prerequisites for the characterization of focused soft x-ray laser beams using profile measurements of the crater created in PMMA.

In this article, we demonstrate the use of PMMA ablation to determine the focal spot intensity distribution of the new FLASH XUV free electron laser [10]. The article is organized as follows. In Section 2 we describe how the ablation threshold and the radiation attenuation length are determined for PMMA using Liu’s method [11]. The extension of this method that enables us to determine the beam profile and the beam diameter at the focal spot is presented in Section 3. Finally, we summarize our experimental findings in Section 4.

2. Determination of ablation process and focal spot characteristics

Liu’s method [11] utilizes surface damage to infer the focused beam characteristics. Linear behavior of the irradiated materials and strongly localized action of absorbed radiation energy are supposed. Initially we assume a Gaussian spatial shape of the FLASH pulses. The beam and material constants can then be calculated from fitting parameters A, B of a linear regression given by formulas S = A+Bln(Epulse) or d = A+Bln(Epulse) applied to measured crater areas S or crater depths d, respectively, as functions of the a pulse energy, Epulse. For the area analysis the focal spot area Sfoc and the ablation threshold Fth are related through [11]:

Sfoc=B
Fth=exp(AB)B

Similarly, for crater-depth analysis the attenuation length lat and ablation threshold Fth are given by [11]:

lat=B
Fth=exp(A)BSfoc

We used 500-nm layers of 495K PMMA deposited on 315-μm-thick silicon chips fabricated by Silson, UK, in our experiments. The samples were positioned in an ultra-high vacuum interaction chamber and irradiated by single ≈25-fs ≈10-μJ FLASH pulses of 32-nm radiation. The beam was focused onto the sample by a grazing incidence elliptical mirror with a focal length of 2 m on Beamline 2. A ray tracing simulation suggested an expected focal spot diameter of 20 μm.

The ablated craters were investigated after the exposures by Nomarski (DIC – differential interference contrast) optical microscopy with BX51M DIC microscope (Olympus, Japan) and by atomic force microscopy (AFM) with a Dimension 3100 scanning probe microscope (SPM) driven by a NanoScope IV controller (Veeco, USA). The AFM measurement was carried out in a tapping mode.

The results of our initial experiments carried out in Oct/Nov 2005 are presented in Figs. 1 and 2. Ablation and beam characteristics evaluated from these measurements according to Liu’s method are summarized in the Table.

Table. Characteristics of FLASH-induced PMMA ablation at 32 nm.

The fluence required for single-shot PMMA ablation induced by 32-nm FEL radiation lies around 2 mJ∙cm-2. The attenuation length lat = (56.9±7.5) nm agrees well with the value of ∼55 nm measured in PMMA with synchrotron radiation [16]. The tightly focused FLASH beam diameter, where the fluence drops to 1/e of its peak value, is 2ρ = (23.8±0.6) µm which is in a good agreement with the expected spot diameter calculated from the focusing system parameters and FLASH output characteristics, and experimentally determined using the atomic gas photo-ionization technique [12].

The PMMA ablation profile was smooth under the given irradiation conditions. There are no bubbles or any other surface imperfections attributed to PMMA thermal modification. The surface roughness as determined by means of AFM was (0.45±0.01) nm before irradiation, whereas the roughness increased to only (3.72±0.06) nm inside a typical crater, and was almost independent of fluence. Very low heat diffusivity D ∼ 0.001 cm2/s of such a dielectric material together with ultra-short pulse duration τ = 25fs result in ultra-short heat diffusion length < 1nm [1]. Moreover, non-thermal processes play a key role in PMMA ablation induced by short-wavelength radiation. PMMA surfaces exposed to intense XUV/soft X-ray radiation remain very smooth even if used source provides nanosecond and/or slightly sub-nanosecond pulses [6–9].

3. Beam profile reconstruction

The results shown above confirm that PMMA is a suitable material for investigation of the short-wavelength femtosecond laser beam ablative imprints. The ultra-low single-shot ablation threshold, smooth ablated surface, highly localized radiation action together with well satisfied Lambert-Beer’s law make it possible to reliably and accurately reconstruct the transverse time-integrated intensity distribution in the XUV/soft X-ray laser beam from the AFM images for intensities down to the limiting PMMA threshold fluence, i.e., the major part of the beam carrying most of the pulse energy.

The Liu method assumes a Gaussian beam profile. We now extend this method to a more general beam profile. Let us suppose the incident field to be of a general form:

I(x,y,z,t)=I0f(x,y,z)g(t),

where z is a direction of light propagation, xy is a plane perpendicular to z parallel to the sample surface, f(x,y,z) is a beam spatial intensity distribution, and g(t) is a pulse temporal shape function. A sudden and well-localized response of a material to the ultra-short pulse radiation is assumed, thus slow thermal effects and low heat penetration are neglected. An experimental proof is shown in Fig. 3 where no feature characteristic for the thermal damage to the PMMA surface can be seen. This allows us to integrate over time thereby removing the time dependency. A spatial integral over the area xy gives the total pulse energy. Slowly varying envelope approximation (SVEA) in z-direction

f(x,y,z)zlat1f(x,y,z)

allows us to neglect the intrinsic fluence variation along the z-axis between the sample surface (z = 0) and the crater bottom due to the large Rayleigh range of the beam (∼1 mm) compared to the crater depth (∼100 nm). Therefore, in z-direction, the fluence decreases down to the ablation threshold Fth following the Lambert-Beer law. The threshold fluence can be expressed as separate factors involving the crater shape d(x,y) and beam profile f(x,y,0):

Fth=F0f(x,y,0)exp(dxylat).

The transverse radiation energy distribution in the sample surface plane, F(x,y,0), can then be expressed in terms of the measured attenuation length lat, the ablation threshold Fth and crater profile d(x,y) through Eq. (5b),

F(x,y,0)=F0f(x,y,0)=Fthexp(dxylat)

On the other hand, the crater profile may be predicted through the beam distribution function, which has been measured for certain XUV sources by various methods, e.g., scintillator-based imaging as reported in [13,14]. However, scintillator response is usually non-linearly dependent on the intensity of short-wavelength laser radiation [15, 16]. This may dramatically affect the XUV intensity distribution reconstructed from the luminescence signal. Therefore it is not easy to get reliable data on the transverse intensity distribution in the short-wavelength laser beam from such a method. Shack-Hartmann/CCD wave-front sensor [17] can also be used to determine such a distribution of XUV/x-ray lasers providing some additional information on the field.

We found that the FLASH facility generates a roughly Gaussian beam creating craters with a paraboloidal shape that can be expressed in polar coordinates as:

d(r)=lat(ln(EpulseEth)r2ρ2),

where d(r) is the depth at radius r, ρ is a focal spot radius, Epulse is the incoming pulse energy, and Eth is the threshold pulse energy.

Furthermore, it should be mentioned that the validity of these shape Eq. (5a), (5b), and (6) are restricted to the fluence range for which thermal and nonlinear effects are negligible. Radiation energy losses due to the surface reflectivity of PMMA were estimated to be less than 0.5% [18] and therefore ignored in our analysis.

Reliable utilization of PMMA for post-exposure beam imaging has been proven in recent experiments in Sept 2006 conducted at the FLASH facility operated well into the soft x-ray spectral region, i.e., at wavelengths shorter than 30 nm. 1-mm thick samples of PMMA, manufactured by Goodfellow (UK), were irradiated with a tightly focused FLASH beam at 21.7 nm. The crater shapes observed by the AFM were elliptical paraboloids (Fig. 3). Equation (5) with an attenuation length of (69.9±7.0) nm has been used to transform the 3-dimensional picture of a PMMA ablative crater to a 3D profile proportional to the real radiation field, focused by a 2-m elliptical grazing incidence mirror onto the sample surface, shown in Fig. 4.

Orthogonal cross-sections of the beam profile in the X and Y directions are shown in Fig. 5. Two different beam radii in the transverse directions can easily be recognized. The beam profile cross sections are well fitted by Gaussian functions with diameter values 2ρx = (11.8±1.0) µm and 2ρy = (21.4±1.6) μm. The diameter of the representative circular beam, calculated as a geometrical average of two values, is 2ρ = (15.8±1.4) μm and follows a decreasing trend with wavelength as compared to the 32 nm result. There are at least three reasons for this trend. The first one is coming from Gaussian beam feature ρ∼(λ)1/2, and the second one is related to the diffraction limit of the focusing optics ρ∼λ. The third one is given by the increasing quality of the beam exiting the undulator as the electron energy (and thereby the photon energy) increases.

4. Conclusions

We have used a surface damage based method [11] to determine the focal spot size of tightly focused FLASH’s beam lasing at 32 nm. The measured diameter of (23.8±0.6) μm corresponds well to the results of photo-ionization measurements [12]. PMMA seems to be a suitable material for the beam characterization from an ablation crater because of strong localization of the photon action in the polymer structure. The low ablation threshold of PMMA irradiated by the FLASH beam (∼2 mJ/cm2 for 25-fs pulses at 32 nm) allows us to reconstruct a major part of the beam using the extended version of the method. Results obtained at 21.7-nm are also reported here. We observed an elliptical focal spot in which the intensity is well described by a bi-Gaussian function. A mean focal spot diameter of (15.8±1.4) µm has been found at 21.7-nm, demonstrating increased beam focusing for the shorter wavelength.
