Abstract

We report a technique for generation of broad and coherent femtosecond (fs) continua that span several octaves from visible to long-wave IR parts of the spectrum (0.4–18 µm). The approach is based on simultaneous amplification of few-cycle pulses at 2.5 µm central wavelength at 80 MHz repetition rate, and augmentation of their spectrum via three-wave mixing in a tandem arrangement of polycrystalline Cr:ZnS and single crystal GaSe. The obtained average power levels include several mW in the 0.4–0.8 µm visible, 0.23 W in the 0.8–2 µm near-IR, up to 4 W in the 2–3 µm IR, and about 17 mW in the 3–18 µm long-wave IR bands, respectively. High brightness and mutual coherence of all parts of the continuum was confirmed by direct detections of the carrier envelope offset frequency of the master oscillator.

Figures (5)

Fig. 1
Fig. 1 Experimental setup. MO, master oscillator; EDFL, pump laser for the single-pass Cr:ZnS amplifier-&-nonlinear converter; L1–3, AR-coated plano-convex lenses (focal lengths 80, 750, 20 mm, respectively); M*, DM dichroic mirrors (see main text and Ref [24].). The main MIR signal (f) is separated from second harmonic (2f) by mirrors DM. The residual pump radiation in 2f-output is suppressed by an OptiGrate Bragg notch filter (BNF). Higher optical harmonics (3f, 4f) are accessed via residual signal in the main f-output. GaSe sample is installed on a 5-axis stage (see main text and Ref [25].); a 4 mm thick YAG Brewster plate (BP) is used for inter-stage dispersion control. IDFG signal and augmented main signal (f*) are collimated by gold-coated 90° off-axis parabola with RFL = 25.4 mm (OAP); spectral components are separated by a set of long-pass filters (LP).
Fig. 2
Fig. 2 Spectra of pulses in f (black) and 2f (red) outputs of the Cr:ZnS laser (presented in log scale, both peaks are normalized to unity). The central part of the f-peak was acquired by a Thorlabs OSA207C. The wing of the f-peak was acquired with higher dynamic range by an Acton monochromator with a 150 g/mm grating, LP 2.5 µm filter, and a Teledyne J14 MCT detector (LN cooled). The spectra were then stitched together. The 2f-peak was acquired with the same monochromator and a Thorlabs InGaAs DET10D detector. Scattered dots show the noise floors. Dashed lines show the wings of the augmented main signal (f*) after propagation trough the GaSe sample (see main text). Peaks (p) at 1.567 µm correspond to residual cw signals of EDFL pump. Vertical arrows show the wavelengths of fCEO measurements. The inset shows the profile of the main output beam at 4.2 W power (taken by DataRay IR camera).
Fig. 3
Fig. 3 Overall spectrum of the continuum. (a) part of the spectrum in linear scale acquired by an Acton monochromator with a 75 g/mm grating, a Teledyne J22 MCT detector (LN cooled), and a set of LPs with 3, 5, 6.7, 10 µm cut-on. Obtained data were normalized to LP transmission and stitched (as shown by different colors). (b), the same spectra are presented in log scale and combined with the high power part of the continuum from Fig. 2. The curves somewhat mismatch because IDFG and f spectra were acquired in different experiments, using different gratings, detectors, and filters. (c), VIS (4f) and NIR (3f) part of the continuum dispersed by a prism (vertical arrow shows the approximate wavelength of the fCEO measurement). (d), a photo of polycrystalline Cr:ZnS during the laser operation.
Fig. 4
Fig. 4 (a) Measured IDFG output power vs. input power at fundamental wavelength measured behind LPs with 3, 5, 6.7 µm cut-on wavelength and presented in log scale. (b) IDFG beam profile measured behind LP 6.7 µm at the maximum 17 mW power. (c) Normalized spectrum of IDFG signal from Fig. 3(a) (shown by grey color) is compared with measured transmissions of LPs with 3, 5, 6.7 µm cut-on wavelength (shown by blue, green, and red colors, respectively).
Fig. 5
Fig. 5 RF spectra of interference beatings between the adjacent comb-like spectra measured in a 10 kHz resolution bandwidth (a Rohde & Schwarz FSEA RF spectrum analyzer) (a) a Thorlabs FL632.8-3 filter and Si APD430A detector, (b) a Thorlabs FB1400-12 filter and an InGaAs New Focus 1611 receiver, (c) a Spectrogon BP4260-150 filter and an InSb Kolmar KISDP-0.1 detector (LN cooled). Measurements were carried out in the course of 2 weeks at the same laser setpoint. Different measured values of the fCEO are likely due to the fluctuations of the environment (temperature in the lab, residual humidity in the laser compartment).
