摘要
考虑温度大幅度变化对工作介质比热容的影响,在激光二极管阵列峰值抽运功率超过104 W的情况下,对热容激光器片状18 mm×18 mm×10 mm Nd:GGG工作介质进行了温度分布的数值计算,并与HR-2型红外热像仪对工作介质端面与侧面测量的温度数据进行了对比分析,取得了一些有价值的结果。
Abstract
The transient temperature distribution of 18 mm×18 mm×10 mm slate Nd:GGG gain medium of the solid-state heat capacity laser pumped by a 104 W laser diode array is numerically calculated to analyze the influence of the large scale temperature variation on the specific heat of Nd:GGG crystal. Through comparing the calculated results with the experimental data, which is achieved with the HR-2 thermal infrared imager from the end face and the side face of the Nd:GGG crystal, valuable conclusions are obtained.
