摘要：
An end-pumped laser scheme using diode-laser stack and additive shaping optics has been implemented. The improvement of laser output power and efficiency of high power diode-end-pumped laser using composite YAG/Nd:YAG/YAG rod instead of simple Nd:YAG rod has been investigated experimentally. Compared to the simple rod laser, the output power and efficiency of the composite rod laser were increased more than 80% and 21.5% respectively, with a more homogenized beam profile. Also the laser threshold was decreased 90% in the composite rod. These results are due to the decrease of thermal effects.
