An Improved Design Method for Diode Laser Longitudinally Pumped Solid State Lasers

以空间相关的速率方程理论为基础，提出了一种改进的激光二极管纵向泵浦固体激光器的设计方法，给出了在一定泵浦耦合方式下，激光器腔模尺寸和输出耦合率最佳值的选取依据。以采用不同耦合系统的端面泵浦Ｎｄ∶ＹＡＧ激光器为设计实例。

A improved design method for diode longitudinally pumped solid state laser was developed based on space dependent rate equation analysis. It provides a useful guideline for optimization of the laser mode sizes and output mirror transmission simultaneously for a given pump configuration. Experimental examples are given for an end pumped Nd∶YAG laser, showing a good agreement with the design predictions.
