摘　　要：为了对四边形激光陀螺进行更为深入的研究,了解其光束特性,运用传输矩阵,得到了四边形激光陀螺的稳定条件,并对四边形激光陀螺内部的高斯光束特性进行了数值计算,得到腔内实际上存在两条高斯光束,它们在两个球面镜处结合在一起。结果表明,球面镜的曲率半径越大,高斯光束的光斑半径越大,光束就越平直,越便于信号的读出。In order to carry out deep research in square ring laser gyro, it is necessary to understand its beam characteristics. Taking advantage of the transmission matrix, the steady condition of a square ring laser gyro was obtained. The electric field distribution in the cavity was obtained by numerical calculation. It is pointed out that there are two Gaussian beams in the cavity, which are combined together at the two curved mirrors. The spot radius will increase with the increase of the curved mirror radii, and the beam will become flatter.
