Abstract
A laser diode-stack end-pumped electro-optically Q-switched Nd:YAG slab oscillator-amplifier system with near-diffraction-limited output is demonstrated by a stable-unstable hybrid resonator. The average power of 100 W at a repetition rate of 10 kHz with a pulse width 14.7ns and average power of 76.3 W at a repetition rate of 5 kHz with a pulse width of 10.2ns are measured. At the repetition rate of 10 kHz and at an output power of 89W, the beam quality factors M2 in the unstable and stable directions are 1.3 and 1.5, respectively.
