Rate equations are developed to describe the behavior of high gain lasers. The solution of these equations for cw operation of such lasers is the same as that obtained by Rigrod. An experimental method is described to find the gain, saturation irradiance, and losses of a given laser. This method is illustrated for a CO(2); laser. The pumping rate and lifetime of the upper laser level of this laser are established. The optimum transmittance of the coupling mirror is also calculated, using the data obtained for the actual gain, saturation, and losses in the laser. Good agreement with experiment is found.
推导了速率方程以描述高增益激光器的行为。此类激光器连续波运转时这些方程的解与里格罗德得到的解相同。描述了一种实验方法来测定给定激光器的增益、饱和辐照度和损耗。以一台二氧化碳激光器为例对该方法进行了说明。确定了该激光器上激光能级的泵浦速率和寿命。还利用激光器实际增益、饱和及损耗的数据计算了耦合镜的最佳透过率。发现与实验结果吻合良好。
