内腔拉曼频移激光器输出光束参量计算
The Calculation of Intracavity Raman-Shift Laser Beam Parameters
摘要
从理论上讨论了内腔拉曼频移激光器输出光束的腰斑大小和位置。首先从矩阵光学出发求出拉曼介质中抽运基频场的光束参量;然后根据Ibison的匹配模理论求出拉曼介质中的斯托克斯参量;最后通过出射光学系统传递矩阵的变换,求出出射拉曼频移光束的参量。为拉曼频移激光器的设计提供了依据。
Abstract
The calculation of the beam waist diameter and it′s position of an intracavity Raman shift laser is discussed. We use optical transformation matrix and figure out the general pump field parameters in the Raman gain medium. And then, according to Ibison′s "matched mode" theory, the Stokes field parameters in the Raman active medium are calculated. By using the optical transformation matrix again, the Raman shifted beam (emitted from the optical system) parameters can be calculated. The results provide a new base for Raman shifted laser design.
