Terahertz Crystals
Crystal for generation and detection of
THz radiation.
ZnTe, GaP, GaAs, GaSe, LiNbO3
Tilted Pulse Front Method
Experimental set up layout. The input laser is split between the pump and the probe beam using beam splitter BS1. The pump beam is used to generate THz using tilted pulse front method in LiNbO3 crystal. The generated THz is steered using four off axis mirror and focused at the ZnTe crystal. The probe beam is used to detect the generated THz via electro optic sampling technique. The THz signal is measured using lock-in amplifier and computer.
GaP 110-cut crystal 10x10x2mm
We demonstrate broadband high-power terahertz (THz) generation at megahertz repetition rates by optical rectification in GaP driven by an ultrafast Yb-based thin-disk laser (TDL) oscillator. We investigate the influence of pulse duration in the range of 50–220 fs and thickness of the GaP crystal on the THz generation. Optimization of these parameters with respect to the broadest spectral bandwidth yields a gap-less THz spectrum extending to nearly 7 THz. We further tailor the driving laser and the THz generation parameters for the highest average power, demonstrating 0.3 mW THz radiation with a spectrum extending to 5 THz. This was achieved using a 0.5 mm thick GaP crystal pumped with a 95 fs, 20 W TDL, operating at 48 MHz repetition rate. We also provide a simple method to estimate the THz spectrum, which can be used for design and optimization of similar THz systems.
