Abstract

Terahertz (THz) pulses with a peak power of 2 kW were generated in a noncollinear phase-matched GaAs crystal at room temperature. Two 200 ns pulses from a dual-beam TEA C O 2 laser were used for difference frequency mixing in the crystal. A comb of narrow lines ( Δ ν ν 10 4 ) was obtained in the 0.5 3 THz range with a step of 40 GHz . By comparing the effective nonlinearity of GaSe with that of GaAs for THz generation, the electro-optic nonlinear coefficient for GaSe was measured to be d eo = 24.3 ± 10 % pm V . Using simulations we show that a 1 kW THz pulse could be amplified by a factor of 2 × 10 4 to a 10 MW level in a 2 m long single-pass free-electron laser.
