Thermal Analysis of Kilowatt Yb~(3+) Double-clad Fiber Lasers
千瓦级掺Yb~(3+)双包层光纤激光器的热分析

The heat dissipation mechanism in Kilowatt double-clad fiber laser is investigated.Meanwhile,the steady-state heat equations with consideration of both convective and radiative heat transfer are constructed.By using the steady-state rate equations and heat equations,the temperature distributions along the fiber for forward pump of 1 000 W and two-end pump of 500 W each side are calculated numerically.The results show that the temperature distribution for two-end pump mode is more even than that for forward ...
