摘要
本文以旋转矢量法为基础,结合异面谐振腔中本征模式的耦合规律及图像旋转特性,推导得到了异面环形激光谐振腔中背向散射光所引起的锁区阈值表达式,研究了异面腔结构参数对于背向散射光及锁区阈值的影响.在左、右旋分量锁区同步变化情况下,实现了通过调控异面腔折叠角α来减小并消除锁区的目的.本文所得结果说明了旋转矢量法分析背向散射光对异面腔激光陀螺锁区阈值的便捷性和准确性.
Abstract
Based on the rotation vector method,this paper combines the coupling rule and the image rotation property of the eigenmode in nonplanar ring resonator to derive expression for the lock region threshold caused by the backscattering light in a nonplanar ring laser resonator and investigate the influence of nonplanar cavity structural parameters on backscattering light and its impact on the lock region threshold.Under the condition that the lock region of left-hand and right-hand components changes synchronously,the objective of reducing and eliminating the lock region is achieved by adjusting the nonplanar cavity folding angle α of the different plane cavity.The results obtained in this paper demonstrate the convenience and ac-curacy of using the rotation vector method to analyze the threshold of backscattering light on the locked area of nonplanar laser gyro.
