| 摘 要： | 采用808 nm光纤耦合输出激光二极管(FCLD)单端端面抽运Nd∶YVO4晶体,采用四镜折叠环行腔,在腔内插入法拉第旋光器和半波片实现激光的单向运转以抑制空间烧孔效应,并在腔内加入标准具,最终实现连续单频1064 nm激光输出.在24.6 W抽运功率时,最高输出功率达到9 W,光-光转换效率为36.6%,M2因子约为1.14,频率漂移约200 MHz.

| Abstract: | The continuous-wave (CW) single-frequency single end-pumped 1064 nm laser with maximum output power of 9 W was experimentally demonstrated. An a-cut Nd:YVO4 crystal was end-pumped by a fiber-coupled laser diode (FCLD) at 808 nm. The four-mirror bow-tie ring cavity with a Faraday rotator and a half wave plate was applied to eliminate the spatial hole-burning effect. A solid etalon was inserted into the cavity to obtain the single-frequency output with M2≈1.14. The maximum output power was 9 W and the optical-optical efficiency was 36.6% with 24.6 W of the incident power. The fluctuation of frequency was about 200 MHz. |
