摘要：

In this paper we report on the characterization of a diode-side-pumped Nd:YAG rod laser operating at 300 W CW output power. The simulated and measured pump energy distributions in the crystal are compared. The thermal lens effect of the Nd:YAG have been experimentally investigated, and its influence on the performance of the laser are discussed. Output power and the beam quality of the laser under different resonator mirrors and rod end-face curvatures have been experimentally studied. The optical-to-optical and electrical-to-optical efficiencies are 28.5% and 11%, respectively. The beam parameter product is 40 mm.mrad and the instability of laser is about 3%.
