LD Pumped Nd:GdVO4/KTP Intracavity-frequency-doubling Laser
Based on the measuring of thermal focal length and 1.06 μm fundamental property of Nd:GdVO4, the intracavity-frequency-doubling property of LD pumped Nd:GdVO4/KTP laser has been studied with a three-mirror folded cavity. When pumped by low power LD laser outputted from a single-fiber with the diameter of 200μm, the green laser has a threshold of 26 mW and an optical-to-optical efficiency of 17.3%. When pumped by high power LD laser outputted from a multi-fiber with the diameter of 1.55 mm, the green laser has a threshold of 200 mW and an optical-to-optical efficiency of 19.35%.
