摘要

近年来，光纤激光系统在光束质量和功率方面有了快速的发展。高脉冲能量和峰值功率要求大有效面积，因此提出了新的光子晶体光纤设计。热光学效应会导致横向模不稳定，这是一种在阈值功率水平上产生的非线性效应。研究了热效应对光纤导流性能的影响。提出了改进的纤维设计方案。

Improved performances of photonic crystal fibers for high power laser operation

In recent years fiber laser systems have shown a rapid evolution in terms of beam quality and power. High pulse energy and peak power require large effective area, so new photonic crystal fiber designs have been proposed. Thermo-optical effects can lead to transverse mode instability, a nonlinear effect that sets in at a threshold power level. The influence of thermal effects on fiber guiding properties is here investigated. Improved fiber designs are proposed.
