Abstract

Laser diode pumped solid-state lasers, which have the advantages of high efficiency, compactness, stability, long lifetime and high beam quality etc, are called all-solid-state lasers. The all-solid-state lasers are widely used in military, industrial, medical, scientific research and information fields. Among the many laser crystals suitable for them, the Nd:YVO4 crystal has attracted much attention because of its excellent properties. At the same time, considering the high damage threshold of the nonlinear crystal LBO, using LBO crystal to realize the frequency doubling output of 1342nm fundamental frequency light of Nd:YVO4 laser is an ideal choice. In this paper, an intracavity frequency doubled Nd:YVO4 red 671nm laser based on LBO crystal is reported, and the parameters of this laser are theoretically analyzed. By using a type II noncritically phase-matched LBO crystal, the operation of a red light laser is realized. The output power of 1.16W at 671nm and optical to optical conversion efficiency of 10.5% were obtained at the pump power of 11.0W. The instability of the output power of this laser is less than 1%, and the output mode of it is TEM00 mode. In the experiment, the V-shaped folded cavity structure is used to improve the mode discrimination ability of the laser. Meanwhile, the reflector at the tip of the V-shaped cavity is used as the output mirror to ensure that the fundamental frequency light passes through the frequency doubling crystal twice, which improves the frequency doubling efficiency to a certain extent. This laser has high stability and can meet the needs of many fields for low power lasers, and the configuration of this source makes it very suitable in some kindred systems.
