摘要
为了研究高功率双包层光纤激光器的热效应,采用模拟计算的方法,推导了掺Yb3+双包层光纤激光器中的温度分布表达式,计算了光纤激光器中的温度分布特性。分析结果表明,光纤的包层半径、传热系数以及抽运方式对光纤中的温度分布有很大的影响。所得的结果为设计实现千瓦级的光纤激光器提供了参考。
Abstract
In order to study thermal effects of high power double clad fiber laser,the thermal distribution of Yb3+-doped double clad fiber laser is derived and calculated. It is shown that absorption coefficient and clad radius of fiber,heat transfer coefficient and pumping method can affect temperature distribution. Conclusions are useful for designing kW level fiber lasers.
