Dual Wavelength Laser Pumped by Rubidium Vapor Laser

双波长激光器在差分吸收激光雷达(different absorption laser radar,DIAL)等诸多领域具有较为广泛的应用。文章使用半导体泵浦的铷激光器泵浦掺钕氟化锂钇(Nd:YLF)和掺钕钒酸钇(Nd:YVO4)晶体,实现了(1047 nm&1064 nm)的双波长激光输出,验证了该种技术路线实现双波长输出的可行性。当半导体激光器的功率为16.05 W时,双波长的总激光功率为102.8 m W,斜率效率为1.27%,两波长功率比为404:1,为双波长激光的产生提供了新的技术路线。

Dual-wavelength lasers have significant applications in differential absorption laser radar(DIAL)and other areas.A dual-wavelength laser output of 1047 nm&1064 nm is achieved by pumping neodymium-doped lithium fluoride Nd:YLF and neodymium-doped ytrium vanadate Nd:YVO4 crystals with rubidium laser pumped by semiconductor laser.And the feasibility of achieving dual-wavelength output of this technical route is verified.When the power of the semiconductor laser is 16.05 W,the total laser power of the dual wavelength is 102.8 mW,the slope efficiency is 1.27%,and the power ratio of two wave is 404:1,which provide a new technical way for the generation of dual-wavelength lasers.
