The He-Sr + laser tube with 7mm inner diameter and 38cm effective excitation length was designed and manufactured. The modified Blumlein circuit was used to realize the excitation of single-wavelength strontium ion compound laser 430.5nm and RM transition laser 1.03μm And the laser oscillates simultaneously, of which the composite laser accounts for the main component.The experimental results of the output power of the composite laser with the working parameters (pulse frequency, charging power voltage and helium pressure) were measured and the experimental results of the maximum laser power of 819mW and 56mW / cm3 were obtained .
