Thermal analysis of the neodymium-doped microspheres array lasers
摘要
Abstract
In order to study the thermal effect of the neodymium-doped microsphere array caused by the pumping laser diode array (LDA ),a thermal-flow-solid coupling model was established with FLUENT6.3.26 software,and the dependence of the temperature of neodymium-doped microsphere array on its size,fluid velocity,pump frequency and the number of microsphere layers was analyzed by means of finite element analysis.Analysis results show that the laser has short thermal recovery time and the cooling effect has nothing to do with the number of layers.The cooling effect of the microspheres in the small size isn't improved by increasing velocity.The maximum one-way optical path difference of Nd3 +microsphere in 2mm and 4mm diameter was 3.1 nm and 51 .9nm respectively at a repetition rate of 1 Hz.The results show that the neodymium-doped microsphere array laser has a highly efficient cooling capacity and is beneficial to the thermal management of a microsphere array laser.关键词
