Generation of High Power THz Radiation in ZnGeP2 upon Femtosecond Ti:Sapphire Laser Pumping

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

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.
