A High-Power Deep-UV Picosecond Laser

Abstract

Toward the development of a high-power deep-ultraviolet picosecond laser, we report the features of a tested laser system and the experimentally observed relation between the fundamental-wave light source and the thermal effects during deep-ultraviolet wavelength conversion. The laser is expected to be operational at 266 nm for about 2000 h based on lifetime tests of 300 h at an average output of 10 W, pulse width of 9.8 ps, and repetition frequency of 200 kHz.
