摘　　要：利用脉冲氙灯抽运的Nd:YAG被动调Q激光器输出的1.06μm激光脉冲泵浦KTP光学参量振荡器,获得脉宽3 ns、单脉冲能量30mJ、中心波长1568nm的信号光输出。信号光脉冲宽度(3ns)比抽运光脉冲宽度(12ns)小得多。实验表明,随着OPO腔长的增加单脉冲输出能量减小,随着抽运光能量的增加单脉冲输出能量增大,对此给予了合理的理论解释。A eye- safe laser pulse with 3 ns pulse duration, 30 mJ output energy and 1568 nm central wavelength was generated from a noncritically phase - matched KTP-OPO pumped by 1.06ban laser. The signal pulse width （3ns） is narrower than the pump pulse width（ 12ns）. The experimental results show that the output energy of signal laser at 1568nm decreases, with the increase of the cavity length of the optical parametric oscillator and the output energy of signal laser at 1568nm increases, with the increase of the pump Lenergy.And a reasonable interpretation is given theoretically.
