Abstract

We present a study on THz generation in lithium niobate pumped by a powerful and versatile Yb:CaF2 laser. The unique laser system delivers transform-limited pulses of variable duration (0.38–0.65 ps) with pulse energies up to 15 mJ and center wavelength of 1030 nm. From previous theoretical investigations, it is expected that such laser parameters are ideally suited for efficient THz generation. Here, we present experimental results on both the conversion efficiency and the THz spectral shape for variable pump pulse durations and for different crystal temperatures, down to 25 K. We experimentally verify the optimum pump parameters for the most efficient and broadband THz generation.

Experimental setup: Yb:CaF2 CPA laser delivers sub-ps, 15 mJ pump pulses; after down-collimation and pulse front tilt, the beam is directed to LN for THz generation. Shown in the inset are the laser spectra produced by different spectral cuts.

Fig. 2.

THz pulse energy normalized to the pump peak power as a function of the laser pulse duration at T=293K and T=25K.

Fig. 3.
Fig. 3.

Cryo-cooled LN gives rise to higher frequencies and threefold higher energy at CT (red curve) in comparison with emission at RT (black curve). The spectra are generated with pump pulses of 380 fs FWHM. The spectral intensities are reconstructed by Fourier transformation of the interferograms shown in the inset.
