抽运腔在LD侧面抽运激光头中的应用
Application of Pump Cavity in LD Side-Pumped Laser Head
摘要
介绍了抽运腔在半导体侧面抽运固体激光头中的应用。运用光线追迹的方法,从理论上分析了抽运腔对抽运光在晶体中的吸收效率和相对强度分布的影响,然后对无抽运腔、有抽运腔、抽运腔内表面经过镀金处理、抽运腔内表面经过抛光和镀金处理四种情况进行了实验研究。从理论模拟和实验结果中可以看出,抽运腔及其内表面的处理质量对激光头输入输出性能有很大的影响。
Abstract
The application of pump cavity in laser diode (LD) side-pumped laser head is introduced. By using ray tracing calculation, the effects of the pump cavity on the absorption efficiency and the intensity distribution of the pump light in the crystal were analyzed. The experiments were carried out respectively under the conditions of with and without pump cavity, with gold-plating pump cavity and with polished gold-plating pump cavity. The result showed that a gold-plating pump cavity greatly improved the output character of the pump head.
