中文摘要:
采用X型谐振腔,实验研究了二极管抽运Nd:CGA激光器的连续和被动锁模激光特性。当Nd:CGA激光器实现连续运转时,采用不同透过率的输出镜优化激光器的连续输出功率。采用透射率为20%的输出镜时,获得了1.8 W的最高连续输出功率,斜率效率达到30.8%,中心波长为1079 nm;采用半导体可饱和吸收反射镜作为锁模元件、透射率为1.6%的平面镜作为输出镜,获得了脉冲宽度为2.7 ps、重复频率为177 MHz的被动锁模脉冲输出。当抽运功率为6.9 W时,获得锁模脉冲的最大平均输出功率为524 mW,相应的光

英文摘要:
The continuous wave (CW) and passive mode-locking features of a diode-pumped Nd : CGA laser are experimentally demonstrated with a typical X-type cavity. Under the CW operation, different output couplers (OCs) were used to optimize the CW output power of the Nd: CGA laser. With the OC of 20% transmission, the maximum CW output power of 1. 8 W is achieved and the slope efficiency is 30. 8% at the central wavelength of 1079 nm. By employing a semiconductor saturable absorber mirror for passive mode-locking, pulses as short as 2. 7 ps with 177 MHz repetition rate are achieved for OC with transmission of 1.6%. The maximum average output power of 524 mW is obtained under a pump power of 6. 9 W. The optical-to-optical conversion efficiency and the slope efficiency are 7.6% and 8.0%, respectively.
