Abstract

The possibility of generating high power terahertz radiation in a nonlinear crystal of zinc germanium phosphide (ZnGeP₂) with pumping in a short-wavelength absorption shoulder of 0.67–2.5 μm is studied in detail. High power femtosecond Ti:Sapphire laser system operating at wavelengths of 800 and 950 nm are considered as a pump source. A peak terahertz radiation power of ~1 kW is obtained.

飞秒Ti：蓝宝石激光泵浦在ZnGeP 2中产生高功率THz辐射

摘要

详细研究了在0.67–2.5μm的短波长吸收肩中泵浦的情况下，在磷化锌锗（ZnGeP ₂）的非线性晶体中产生高功率太赫兹辐射的可能性。工作在800和950 nm波长的高功率飞秒Ti：蓝宝石激光系统被认为是泵浦光源。获得的峰值太赫兹辐射功率约为1 kW。
