Abstract

This paper reports a no-water-cooling side-pump rod amplifier and has more detailed simulation calculations. Study on the pump light distribution in the rod medium and thermal stress, a nearly flat-top gain distribution and low thermal effect are obtained through design and simulation. The size of rod medium is Φ18×150mm, pump distance is 5mm, there are 15 diode lasers on the side of the rod medium in a spiral staircase arrangement, and the misalignment angle of each laser diode is 24°. This paper provides many references for the no-water-cooling laser system and broadens the application of large-module laser amplifiers.
