In this Letter, a high-power diode-side-pumped Nd:YAG laser emitting at is described. The output characteristics of the laser using the different output couplers for both the cw mode and the Q-switched mode have been studied. With a pumping power of , the average output power decreases from at (slope efficiency 21.2%, optical conversion efficiency 10%) at . The highest peak power is up to with the pulse duration of at the repetition rate of . When operated in cw mode, the output power of was achieved, corresponding with the optical slope efficiency of 36%.
