| Abstract: | In this paper, the characteristics of diode-side-pumped ceramic Nd:YAG electro-optic Q-switched laser were studied. A uniformly side-around arranged compact laser-diode-array (LDA) pumping structure with micro-channel heat-sink cooling was used in this laser. In a 5 mm×75 mm sized and 1 at.-% doped Nd:YAG ceramic rod, with electro-optic Q-switch repetition rate of 100 Hz, and input energy of 416 mJ per pulse, a laser with the output energy of 50 mJ per pulse at 1064 nm, pulse duration of 12 ns, and slope efficiency of 24% was obtained. The insertion losses of polarizer, KD*P and λ/4 wave-plate were measured and analyzed. The temporal waveform and the intensity distribution of output laser were measured. |
