摘要
讨论了端面泵浦二极管泵浦固体激光器中泵浦光束空间分布对二极管泵浦固体激光器性能的影响.通过计算,发现泵浦光的分布半径、泵浦光对对称性的偏离程度会严重影响到振荡光的阈值、输出功率和斜效率,并绘制了相应的变化曲线.计算还表明,单独利用泵浦光的M2因子判断泵浦效果并不合适.通过数值计算,还分析了泵浦光空间分布对振荡光光束质量的影响.
This paper discusses how the distribution of pumping light affect the diode pumped solidstate laser. It has been found that the dissymmetry and radium of the pumping beam are very important factors related to the determination of the threshold, output power, slope efficiency and the oscillating laser shape. Calculation also reveals that the factor M2 is not adequate to appraising a pumping systems quality.
