456nm solid state blue pumping 360nm all solid-state ultraviolet laser

Abstract

The invention discloses a 456nm solid state blue pumping 360nm all solid-state ultraviolet laser and relates to an all solid-state laser. The 456nm solid state blue pumping 360nm all solid-state ultraviolet laser is provided with an all solid-state 456nm blue laser, a plano-convex coupled input mirror, a plane input mirror, a Pr:GVO4 laser crystal with a temperature control device, a laser outputmirror, a frequency doubling crystal and a folding endoscope. The plano-convex coupled input mirror is arranged at the output end of the all solid-state 456nm blue laser; the input end of the plane input mirror is connected with the output end of the plano-convex coupled input mirror; the input end face of the Pr:GVO4 laser crystal with the temperature control device is connected with the plane input mirror; the laser output mirror is arranged at the output end of the Pr:GVO4 laser crystal to be taken as the output mirror of ultraviolet lights; the frequency doubling crystal is arranged at the back end of the laser output mirror; and the folding endoscope is arranged at the back end of the frequency doubling crystal to be taken as the total reflection low back mirror of the ultraviolet lights.

Description

technical field [0001] The present invention relates to an all-solid-state laser, in particular to a 456nm solid-state laser pumping Pr:GVO 4 Frequency-doubled 360nm ultraviolet all-solid-state laser. Background technique [0002] Ultraviolet lasers have special application prospects in the fields of material processing, industrial manufacturing, semiconductor performance testing, and laser holography. So far, these ultraviolet lasers mainly include pulsed excimer lasers and continuous gas lasers (such as 363nm argon ion lasers and 320nm helium lasers). -cadmium lasers), and the 355nm pulse tripled Nd:YAG / Nd:YVO developed in recent years 4 solid-state lasers. Among them, excimer lasers have complex systems, low efficiency, and short service life; gas ultraviolet lasers are bulky, low in efficiency, and low in output power (for example, the maximum output power of the argon ion laser with a wavelength of 363nm is only 150mW for the INOVA300C of Coherent in the United States...
