Abstract

We establish a one-to-one mapping between the local phase slip and the spatial position near the focus by scanning a thin jet along the propagation direction of laser beams. The measurement shows that the optimal phase of terahertz can be utilized to characterize in situ the spatially dependent relative phase of the two-color field. We also investigate the role of the Gouy phase shift on terahertz generation from two-color laser-induced plasma. The result is of critical importance for phase-dependent applications of two-color laser-field, including high-order harmonic and terahertz generation.

Figures (7)

Fig. 1
Fig. 1 Schematic diagram of the experimental setup. DWP: dual-wavelength plate; WGP: wire grid polarizer; SM: spherical mirror; PM: parabolic mirror; PBS: polarizing beam splitter.
Fig. 2
Fig. 2 (a) The interference signal of second-harmonic measured with (blue dots) and without (red squares) gas jet. (b)The modulation of THz intensity versus the relative phase between the two-color laser fields. Red dots are the experiment data and the black line is the fitted curve. The zero point of relative phase is chosen arbitrarily in both figures.
Fig. 3
Fig. 3 (a) The THz yield at optimal phase varies with the gas jet position. The red dots is the measured THz intensity and the black line guides the eyes. The fundamental laser intensities at the focus is estimated to be ∼ 1.8 × 1014W/cm2. (b) The dispersion-induced relative phase ϕd varies with the jet position to maximize THz intensity. The red dots is the experimental ϕd at different z-position along the propagation of two color lasers. The black line is the calculated relative phase ϕG induced by the GPS.
Fig. 4
Fig. 4 The optimal phase measured in different fundamental laser intensities (a) and intensity ratios (b). The reference phase (zero point) is chosen that in the low laser intensity.
Fig. 5
Fig. 5 (a) THz waveforms measured at different jet positions along the propagation of laser beams. The THz intensity at the focus is maximum in the left while minimum in the right, corresponding to different relative phases ϕ d 1 and ϕ d 2. (b) The phase dependence of THz generation from the thin jet at the focus (left), from the coherent superposition of different thin jet positions near the focus (middle), and from low-pressure argon in a chamber (right).
Fig. 6
Fig. 6 THz waveforms (a) and intensity (b) vary with the relative phase of two-color fields. The phase-gating cannot turn off the THz radiation completely due to the relative phase slippage along the long gas plasma. This phase slippage results in the non-zero amplitude of THz radiation at any relative phase as shown with black line in (a) and noticeable background as shown in (b).
Fig. 7
Fig. 7 THz generation driven by the circularly polarized two-color field. (a) The polarization of THz waveforms rotate with the relative phase of two-color fields when the gas jet is placed at the focus. (b) The ellipticity of THz wave increases with the higher gas pressure.
