摘　　要：文中报告了掺Yb3+双包层光纤激光器的理论和实验研究工作。在稳态条件下,基于速率方程推导了掺Yb3+双包层光纤激光器在强泵浦条件下的简化型解析解。实验上,利用975 nm大功率半导体激光作为泵浦源,采用单端泵浦技术,获得了88 W波长为1 082.4 nm的连续激光输出,斜效率高达84.4%。实验结果与理论的简化型解析解相比较,两者基本一致。Studies of Yb3+-doped double-clad fiber lasers(Yb-DCFL) are reported.Under the steady-state conditions,a simplified analytic solution is deduced in the strongly pumped condition based on the rate equations.Using a 975 nm laser diode(LD) as the pump source,we obtained 88 W CW output laser power at a wavelength of 1 082.4 nm is obtained.The slope efficiency is as high as 84.4%.The experimental results and theoretical ones from our analytic solution match very well.
