摘要
基于被动锁模技术,设计了结构紧凑的Z型谐振腔,采用半导体可饱和吸收镜作为被动锁模元件,利用激光二极管泵浦增益线宽较宽的Nd∶YVO4晶体,最终实现了连续锁模的脉冲输出.在输入功率为8.20W时,获得了输出功率为1.72W的1 064nm连续锁模脉冲激光输出,光-光转换效率达21%,锁模脉冲重复频率为110MHz.
Based on passive mode-locking technology, Z-type resonant cavity was designed. Using semiconductor saturable absorber mirror as the passive mode-locking component and a diode-pumped solid-state laser to pump Nd L YVO4, continuously mode-locking pulse output was realized. When input power was 8.20 W, 1 064 nm continuously mode-locking pulse output power was 1.72 W, light-light conversion efficiency was 21%, mode-locking pulse repetition frequency was 110 MHz.
