Gain-Loss Ratio of Small Ring Lasers
摘要
增益损耗比是气体激光器的重要工作参量之一,它对激光陀螺的整体设计和实际性能有很大的影响。小尺寸环形气体激光器具有较宽的模间隔,为这一参数的测量提供了便利。根据理论推导,得出增损比的简化计算公式。提出一种测量增损比的实验方法,并对大批量的激光器进行实验研究。实验结果表明,在现有的高水平光学加工工艺和调腔精度下,环形激光器的平均增益损耗比已经达到3.55。
Abstract
Gain-loss ratio is an essential parameter of gas lasers and has a substantial effect on the design and performance of ring laser gyroscopes. Small ring gas lasers have wide mode spacing; therefore, it is convenient to measure the gain-loss ratio. A simple formula for calculating the gain-loss ratio is derived theoretically. Then, an experimental method is proposed to measure this parameter, and experiments are conducted for a large number of lasers. Results show that by taking advantage of precise optical machining and cavity alignment, the average gain-loss ratio of a ring laser can reach up to 3.55.
