Study of High-power Diode-pumped Solid-state Laser

Diode-pumped solid-state lasers are replacing flashlamp-pumped solid-state lasers and are widely used in industries. A side-pumped Nd:YAG laser is reported in this paper. Output laser power of 360W and stability of ±1% are obtained though the series-oscillation resonator using two diode pump modules. There are totally 30 diode laser bars used in each module and 5 diode laser bars are placed around the Nd:YAG rod. A flat rear mirror and a flat output coupler are used as laser resonator. The structure and output characteristics of the laser are studied in detail. It is shown that the laser is
