| 摘 要： | 为了研究LD抽运晶体在实际谐振腔中,LD变化半径在晶体中产生的热效应,采用了理论上与理想模型下所求解的结果相比较的方法,得到了当输出功率为15W时,抽运端面中心获得199.545℃最高温升和1.33μm最大热形变量、实验值与理论值基本一致的结果.结果表明,这种新的研究方法可以更准确地应用到其它激光晶体热问题的研究中,为有效解决激光系统热问题提供了理论依据. |

| Abstract: | In order to study the thermal effect of Nd∶GdVO4 crystal pumped by variable radius LD bar in a resonator fiber,the theoretical values and experiment values were compared and they're largely in accord with those based on the new physics model with variable Gaussian radius. The results showed that the maximum temperature rise of 199.545℃ and the maximum thermal distortion of 1.33μm could be obtained in the center of the pump end surface when the Nd∶GdVO4 laser crystal was pumped by a laser diode with an output power of 15W from the center of end face. This new method can be applied in the research of the other thermal problems of laser crystal and offer theoretical basis for solving the thermal problems in laser system effectively. |
