Research on Three-Wavelength Diode Pumped Solid State Laser of 0.5 μm Waveband
In order to improve the stability of the 561 nm yellow laser output power by the Nd:YAG/LBO intra-cavity frequency doubling, the birefringence filter (BF) is inserted into cavity. Meanwhile, the 556 nm and 558 nm single line laser outputs are obtained by tuning the alignment angle of the BF. When the pumping power of Nd:YAG crystal is 5 W, and the thickness of BF is 2 mm, the fundamental beam of the single line laser is obtained by tuning the alignment angle of the BF. Then, the yellow laser is obtained by LBO intracavity-frequency-doubling. At the incident pumping power of 5 W, the output power at 556, 558, 561 nm are 256, 189, 227 mW, and the corresponding light-to-light conversion efficiency are 5.12%、3.78% and 4.54%, respectively.
