摘　　要：报道了利用连续激光二极管端面泵浦被动Q开关固体Nd:YAG激光器,研究设计了实用光学耦合系统,采用初始信号透过率为80%的Cr4+:YAG晶体实现被动调Q,采用平凹直线腔结构,高重复率调Q激光器中获得了稳定的1 064 nm窄脉冲激光输出。当泵浦功率为5 W,重复率为5 kHz时,获得的输出单脉冲能量平均为118μJ,脉冲宽度5 ns,光-光转换效率为15.7%。此性能激光器可用于珠宝雕刻等领域。The CW diode-end-pumped solid-state Nd:YAG laser using a prece of Cr4+:YAG passively Q-switched crysta1 was reported.Optics coupling systerm was studied and designed,used a Cr4+:YAG crystal with the singal transmission of 80% and a plane-concave cavity.Under the incident power of 5 W and repetition rate of 5 kHz,the maximum laser output enegey is 118 μJ,pulse width is 5 ns,and conversion efficiency from light to light is 15.7%.It can be used in carving jewellery field.
