摘要
推导了掺Yb 光纤激光器中激射波长与掺杂光纤长度、掺杂浓度等的关系式。依据所得到的关系式,在981.5 nm 半导体激光抽运的掺Yb 环形腔石英光纤激光器中,获得了中心波长在1053nm 的激光输出。光抽运阈值功率为1.85 m W。激光半功率宽度(FWHM)为5 nm ,输出功率为104μW,斜率效率为3% 。激光空间模式为基横模。
Relationship among lasing wavelength, fiber length and dopant concentration has been deduced in Yb 3+ doped fiber laser. Based on the relationship, a single spatial mode ring fiber laser operating at 1053 nm pumped by a 981.5 nm, laser diode has been achieved with a linewidth of 5 nm, pumping threshold 1.85 mW and slope efficiency 3%.
