高功率双包层光纤激光器热效应及功率极限
Thermal effect and power limit in high power double-clad fiber laser
摘要
Abstract
According to the steady-state heat conduction equation,the temperature distribution in the high power double-clad fiber laser(DCFL) has been analyzed.The influence of fiber size,cooling-boundary condition and pump power on temperature distribution are discussed based on the analytic solution.The theoretical maximum output power with given parameters is obtained.The maximum power of a commonly used DCFL is limited by the melting point of the material and the non-linear effect.The bottlenecks can be easily determined so as to come up with effective improved shemes,such as weakening or eliminating the linear effect,raising the heat-resistant of outer-clad and improving the cooling method.关键词
