摘　　要：对采用四频差动法偏频的环形激光器中光场偏振度进行了计算和讨论。光场的偏振用圆基坐标下的琼斯矩阵表示。光场的偏振度由反射膜片和水晶片的光学性质决定,在环形腔中的不同位置处,光场的偏振度不同。Degree of polarization of the optical modes in ring lasers are calculated and discussed. Polarization of the optical modes is expressed by Jones matrix under circular coordinate.Degree of polarization of the optical modes,which is decided by the optical property of the thin film and the crystal, depends on the optical modes’ positions in ring cavity.
