四频差动激光陀螺辐射捕获效应的理论研究

为了研究四频差动激光陀螺误差因素，辐射捕获效应需要考虑。从激光器辐射捕获物理机制出发，引入s因子表征烧孔被部分填充，结合自洽方程组推出新的修正公式，解决了Aronowitz修正方法与实验相矛盾之处。同时基于四模激光器模型，从能级跃迁的物理本质出发，考虑了模间精细耦合作用特点，得到了四频差动激光陀螺的辐射捕获效应修正公式，并做了双同位素情形下的修正。这对激光陀螺的理论研究有参考价值。

The theoretical study on radiation trapping effects correction of four frequency differential laser gyro

For the study of error factors in four frequency differential laser gyro, the radiation trapping effects need to be considered. From the physics mechanism of laser radiation trapping effects, the s coefficient was introduced to represent the burning holes were partly filled in, and the new correction formulas are derived from the self-consistency equations, which can solve the contradiction between the Aronowitz’s method and the experiment results. Then, based on the four lasers mode, the fine mode coupling effects were considered from the physics mechanism of atom transition. Finally, the radiation trapping effects correction formulas of four frequency differential laser gyro are obtained in the case of two isotopes, which can be helpful to the theoretical research on four frequency differential laser gyro.
