Abstract

The invention relates to all-solid-state lasers, in particular to a blu-ray-pumped praseodymium-doped yttrium lithium fluoride all-solid-state 670nm red laser. The blu-ray-pumped praseodymium-doped yttrium lithium fluoride all-solid-state 670nm red laser comprises an all-solid-state 444nm InGaN blu-ray semiconductor laser, a focusing lens, a collimating lens, a planar input cavity mirror, a Pr:YLF laser crystal, a Fabry-Perot etalon and a concave output cavity mirror, wherein the focusing lens is arranged at an output end of the all-solid-state 444nm InGaN blu-ray semiconductor laser, an input end of the collimating lens is positioned at an output end of the focusing lens, the planar input cavity mirror is arranged at an output end of the collimating lens and serves as an input cavity mirror of the laser, the input end face of the Pr:YLF laser crystal is connected with the planar input cavity mirror, the Fabry-Perot etalon is arranged behind the Pr:YLF laser crystal and serves as an adjustment tool for guaranteeing that the laser outputs 670nm red ray, and the concave output cavity mirror is arranged at an output end of the Pr:YLF laser crystal, serves as an output cavity mirror of the laser and serves as an output mirror of the 670nm red ray.

Description

technical field [0001] The invention relates to an all-solid-state laser, in particular to a red-light 670nm all-solid-state laser pumped by blue light and praseodymium-doped yttrium-lithium fluoride. Background technique [0002] The red 670nm all-solid-state laser pumped by blue light pumped with praseodymium-doped yttrium-lithium fluoride is a kind of all-solid-state laser that has been widely studied. Pr:YLF laser crystal has laser lasing at four wavelengths of 640nm, 670nm, 698nm and 720nm in the red light band, and the laser lasing at 640nm, 698nm and 720nm is stronger (see literature Teoman Gün, *Philip Metz, and Günter Huber ,"Power scaling of laser diode pumped Pr 3+ :LiYF 4 cw lasers: efficient laser operation at522.6nm, 545.9nm, 607.2nm, and639.5nm", OPTICS LETTERS / Vol.36, No.6 / March 15, 2011 and Zhe Liu, et al."Diode-pumped Pr 3+ :LiYF 4 continuous-wave deep red laser at 698 nm", Journal of the Optical Society of America B / Vol.30, Issue2 / January 9, 2013).
