A method and setup for optimizing the configuration parameters of a diode-side pumped module is presented. The method is used to investigate the effects of some configuration parameters of the module on the gain distribution in the laser rod and the absorption efficiency of the side-pumped module. These configuration parameters include the distance between the LD and side surface of the laser rod, the concentration of the active medium and the number of the pump light surrounding the laser rod et al. The effects of the distance between LD and the side surface of a Nd: YAG rod on the gain distribution and the absorption efficiency are investigated. The configuration parameters of the module are optimized.
