摘　　要：用求极值方法得到激光介质最佳吸收密度的计算公式,它是纵向抽运固体激光器获得最佳输出的极值条件。由此可以计算相应的元件合适长度和输出镜合适透过率。还讨论材料的吸收对激光性能的影响,建议采用α_p^2/α_1为Q值,作为纵向抽运激光材料的品质因素。The formulas for calculating the optimum absorption density of a laser medium, which is the condition for maximum output of longitudinally pumped lasers, have been obtained by means of maximizing the output and slope efficiency of them. The appropriate length of solid-state laser medium and suitable transmittance of the ou-tput mirror can be calculated as well. The material absorption effect on the laser performance is discussed and the Q-value( =αp2/α1) as a quality factor for a material. being used in a longitudinally pumped laser is suggested.
