摘　　要：通过实验的方法对掺Yb^(3+)双包层光子晶体光纤激光器的功率和温度特性进行了研究。利用长度为8 m的双包层光子晶体光纤(PCF),在双端泵浦源光功率为260 W时,获得213.4 W的高功率单模连续输出,光-光转换效率为82.1%;同时,由于激光器采用低吸收系数光纤泵浦,光纤温度未出现明显的非线性现象,且在最高输出功率时,光纤表面最高温度仅为32℃。该报道进一步验证了低吸收率的双包层光子晶体光纤的优良特性,若进一步优化耦合系统及增大泵浦激光器的泵浦功率,该光纤有望获得更好的性能。In this paper, the power and temperature characteristics of yb3＋-doped double-cladding pho- tonic crystal fiber （PCF） laser are studied by experimental method. In the experiment,213.4 W single mode continuous-wave output power is achieved from the double-cladding photonic crystal fiber laser with 8 m length at the dual-end pumping power of 260 W. The optical to optical conversion efficiency is as high as -82.1%. There is no nonlinear effect observed because of the low absorption coefficient plao- tonic crystal fiber pump laser,and the highest surface temperature of the photonic crystal fiber is just 32 ℃ at the maximum output power. This reports further validate the excellent properties of the low ab- sorption coefficient double-cladding photonic crystal fiber. If the coupling system of photonic crystal fiber laser is further optimized and the dual-end pumping power is increased, the better performance can be expected to gain.
