【摘要】 对激光二极管侧面泵浦Nd∶YAG激光器的热效应进行了分析。由热传导方程得出YAG晶体内的温度分布 ,分析了激光介质中的热应力和热应力双折射 ,并得到YAG的热焦距及激光束腰和远场发散角随泵浦功率的变化图形。更多还原

【Abstract】 The thermal effects of laser diode side-pumped N d∶YAG laser are studied.Temperature distribution in YAG crystal is obta ined by heat exchange equation,thermal stress and thermal stress birefringence in YAG crystal are analyzed,the figures of thermal focus length,laser waist and far-field beam divergent angle dependence on pump power are received.更多还原
