| 摘 要： | 针对板条、盘片和管状激光器由于不是圆形光斑而难于聚焦及棒状激光器的热效应问题,设计了一种双半圆柱激光器。双半圆柱激光器能实现圆斑输出,而热效应要优于棒状激光器。用ANSYS软件进行的热效应数值模拟分析表明,双半圆柱状激光器比棒状激光器最高温度低25℃左右,最大温差低11℃左右,最大热应力在棒状激光器的60%以下。

| Abstract: | We design a double-semi-cylinder laser in order to solve the problem that the beams of slab laser,disk laser and tube laser are difficult to focus because they are not round and the problem of rod laser with a poor thermal effect.The beam of double-semi-cylinder laser can be round and its thermal effect is much better than rod laser.Results of numerical analysis with ANSYS software show that the highest temperature of double-semi-cylinder laser is about 25 ℃ lower than that of rod laser;its largest temperature difference is about 11 ℃ lower,and its largest thermal strain is less than 60% of that of rod laser. |
