Abstract
A low-power microchip seed laser with a pulse duration of is amplified by two single-pass bounce amplifiers. The microchip is a semiconductor saturable absorber mirror (SESAM)-based and passively Q-switched laser with 10 mW output power at a repetition rate of 100 kHz. The first bounce amplifier delivers an average power of 12 W with pump power of 55 W, corresponding to an optical–optical extraction efficiency of 22%. The output power from the second amplifier is 32 W, corresponding to pulse peak power of and pulse energy of . The beam quality factor is 1.25 in the horizontal direction and 1.20 in the vertical direction. The investigations offer a high-peak-power master oscillator power amplifier with both high gain and high beam quality. The all-solid-state laser system is flexible, robust, and cost effective, showing attractive potential for further applications.
