计算模拟了激光二极管侧面直接抽运方式 ,讨论了抽运距离和介质吸收系数等参数对抽运均匀性的影响 ,并近似地给出定量结果。证明只要选取适当的抽运参数 ,采用侧面直接抽运方式也能获得较好的抽运性能和激光输出 The model of direct pumping on the side of laser diode was simulated. The influence of parameters such as pumping distance and medium absorption coefficient on pumping uniformity was discussed and the quantitative results were given approximately. Prove that as long as the appropriate pumping parameters selected, the use of direct pumping side of the way can also get better pumping performance and laser output
