| Abstract: | An alignment-free resonator is used in diode pumped solid-state laser (DPSL). A compact anti-maladjusted passive Q-switched DPSL has been developed by quasi-CW diode uneven side-pumping, and using Cr 4+∶YAG passive Q-switch, conductive-cooling, KTP frequency doubling. The laser specifications are as follows: The wavelength is 0.53 μm with flattened Gaussian beam at far field, the energy is 52.2 mJ/pulse, the output stability is 0.5%, total efficiency is 3.4%, the pulse width is ～6 ns, the repetition rate is 10～40 Hz, and the divergence angle is 2.3 mrad. |
