摘要

利用一种高效的二极管侧泵浦Nd:YAG/Cr4+:YAG调q激光器，研制了一种高脉冲能量的人眼安全激光器。我们利用单片KTP晶体作为光学参量振荡器(OPO)晶体，并形成外腔OPO结构。基于1064 nm的高效Nd:YAG激光振荡器，脉冲能量为30 mJ，在脉冲宽度为6 ns的情况下，获得1573 nm处的OPO能量为13.3 mJ，对应的OPO转换效率为44.3%。

Over ten-millijoule eye-safe laser generation by extra-cavity optical parametric oscillator driven with a diode-pumped Nd:YAG/Cr4+:YAG Q-switched laser

An efficient diode-side-pumped Nd:YAG/Cr4+:YAG Q-switched laser with a convex-concave resonator is employed to develop a high-pulse-energy eye-safe laser. We utilize a monolithic KTP crystal to be the optical parametric oscillator (OPO) crystal, and to form an extracavity OPO configuration. Based on the efficient Nd:YAG laser oscillator at 1064 nm carrying a pulse energy of 30 mJ, the OPO energy at 1573 nm of 13.3 mJ is obtained with a pulse width of 6 ns, corresponding to an OPO conversion efficiency of 44.3%.
