高功率光子晶体光纤激光器实验研究
Experimental investigation of high power photonic crystal fiber laser
摘要
利用F-P谐振腔实验研究了高功率掺Yb3+光子晶体光纤激光器。使用915 nm和976 nm两种波长的泵浦源进行双端泵浦,在23 m长的双包层光子晶体光纤中获得了552 W的连续单模激光输出。该激光器的斜率效率约为76%,光-光转换效率为56%,光谱中心波长为1 078 nm,光束质量平方因子为1.2。
Abstract
A high-power Yb3+-doped photonic crystal fiber(PCF) laser based on Fabry-Perot cavity structure was studied.The laser was two-end pumped by two pumping sources at 915 nm and 976 nm,respectively,and a single-mode continuous-wave laser of 552 W was obtained.The laser had a slope efficiency of 76% and an optical-to-optical conversion efficiency of 56%.The central wavelength of the laser was 1 078 nm and the beam quality factor was 1.2.
