Generation of 100-Ghz Radiation in Lithium Niobate Driven by 4.7-Ps, 22-Mj, 1030-Nm Yb:YAG Laser Pulses

A cryogenically cooled Yb:YAG amplifier with 4.7-ps laser pulses is employed to generate 100-GHz pulses in lithium niobate via optical rectification. We obtained a high efficiency ~0.05% at 300 K, close to the theoretical prediction.
