Discussion of damage induced by trigger pulse at different repetition frequencies in GaAs PCSS's

Abstract

The paper focuses on the light damage induced by nanosecond laser pulse with 1.06µm wavelength at high repetition frequencies in switch materials by comparing the resistivity values when the switch is on/off, discusses the damage mechanism. Experiment indicates that input laser with different repetition frequencies may cause different temperature rising speeds on the surface material, when the laser repetition frequency less than 1 kHz, the temperature accumulation effect in the material dose not perform significantly, and When the pulse laser is at high repetition frequency, the temperature rising rate in the laser irradiation area gets faster.
