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。
In theory, the cavity size and position of the output beam of an internal cavity Raman shift laser are discussed. Firstly, the beam parameters of the fundamental frequency field in the Raman medium are obtained from the matrix optics. Then the Stokes parameters of the Raman medium are obtained according to the Ibid’s matching mode theory. Finally, through the transformation of the transfer optics system, Find out the parameters of the Raman shifted beam. It provided the basis for the design of Raman shift laser.
