摘要:
采用两台大功率光纤输出半导体激光器端面泵浦两块Nd∶GdVO4晶体,以声光Q开关作为腔内调制元件,用对称结构双晶体串接平行平面谐振腔.在注入泵浦功率为66 W,重复频率为100 kHz时,获得10 W的大功率准连续1.34 μm激光输出,斜率效率为18.3%,脉冲宽度为96 ns,激光输出光束发散角约为衍射极限的2倍.
Abstract:
A high power diffraction-limited quasi-continuous-wave diode-end-pumped 1.34 μm Nd∶GdVO4 laser was demonstrated.The laser consisted of two 808 nm LDs as the pump sources,two Nd∶GdVO4 crystal as laser gain mediums,an AO Q-switch as intracavity modulator and a symmetrical twin-crystal plane-parallel cavity.At incident pump power of 66 W and pulse repetition of 100 kHz,a maximum output power of 10 W was obtained,with slope efficiency of 18.3% and pulse width of 96 ns.And the measured laser beam divergence is about two times of the diffraction limitation.
