Title: Short pulse and high repetition rate Q-switched Yb:YAG microchip laser
Abstract: In this paper, we report a diode-pumped passively Q-switched Yb:YAG laser that is an excellent candidate for a ladar master oscillator. This microchip laser has 1 ns pulse duration, 68 μJ pulse energy, 700 mW average power, 10 kHz repetition rate, and 29% optical slope efficiency. Additionally, the microchip oscillates in the fundamental TEM<sub>00</sub> mode. The peak power was measured as high as 66 kW. We compare the pulse shape and duration, and the beam quality to simulation. We study the effects of Q-switch absorption, output coupler reflectivity, cavity length, and pump power on the laser's pulse duration, pulse energy, average power, and repetition rate.
