LD Side-Pumped Nd∶YVO4 532 nm Quasi-Continuous Green Laser
The LD side-pumped Nd∶YVO4 532 nm quasi-continuous green laser is reported. The acousto-optic Q-switched operation and the laser diode side-pumped Nd∶YVO4 laser are used to get high-power linearly polarized 1064 nm laser output. High-power 532 nm green laser output is achieved by typeⅠphase-matched LiB3O5 (LBO) as second harmonic generation crystal. An average output power of 23.5 W at 532 nm is obtained under the condition of input current of 30 A, the repetition rate of 20 kHz and the 1064 nm fundamental wave of 33 W. The optical-optical conversion efficiency is up to 71.2%. The pulse width is 44.3 ns and the polarization ratio is 254∶1.
