| 摘 要： | 计算了第Ⅰ类、第Ⅲ类边界条件下灯泵浦单斜晶系激光晶体垂直棒轴截面上的温度分布,结果表明,在第Ⅰ类边界条件下,温度分布为径向抛物线函数,等温线是圆;对于第Ⅲ类边界条件,温度分布是椭圆或双曲线函数,等温线是椭圆或双曲线。主热导率差别越大,冷却剂冷却效率越弱,偏离圆越严重,提高冷却剂的冷却效率将减小这种偏离。

| Abstract: | For first and third class boundary condition the temperature distribution of monocline laser crystal in a cross section perpendicular to rod axis during the lamp pumping process is calculated in this paper. It is shown that the temperature distribution exhibits radial parabola function and the isothermal line is circularity for first class boundary condition,whereas it is elliptic or hyperbolic function and the isothermal line is ellipse or hyperbola for third class boundary condition. The larger the difference between the principal thermal conductivity is and the lower the cooling efficiency of cooling agent is,the larger the difference with circularity is. Increasing cooling efficiency of cooling agent the difference with circularity will be decreasing. |
