Abstract

Spectroscopy Electronic Optical and Magnetic Materials Instrumentation Atomic and Molecular Physics and Optics Computer Networks and Communications
In previous studies, KTiOPO4 (KTP) shows higher laser damage resistance and larger figure of merit for THz parametric generation [1,2]. To generate high-power THz radiation, it is possible to perform pulsed difference frequency generation in a bulk KTP crystal [3]. Recently, we have also reported an off-axis THz parametric oscillator (OTPO) with unprecedented SPS gain in lithium niobate [4]. In this work, we employ a y-cut KTP slab crystal as an OTPO and seed it with a pulsed signal from a KTP THz parametric generator (TPG) to generate THz radiation with tens of kW power.
