掺杂Yb3+的LiYF4和Y3Al5O12反斯托克斯荧光冷却对比研究
Comparison of Yb3+-doped LiYF4 and Y3Al5O12 in anti-Stokes fluorescence cooling
摘要
Abstract
Laser-induced solid-state anti-Stokes fluorescence cooling has important application value in the fields of all-solid-state cryogenic optical coolers and radiation balance lasers.Among many fluorides and oxide crystal materials,Yb3+-doped LiYF4(YLF)and Y3Al5O12(YAG)crystals stand out for their excellent laser cooling performance.Accordingly,in this study,the spectral properties and anti-Stokes fluorescence cooling properties of Yb3+and YAG crystals with 7.5%doping concentration were compared and analyzed in detail under the same conditions.The results show that compared with YAG crystal,YLF crystal has a smaller minimum achievable temperature,and hence,a more feasible candidate for use in cryogenic coolers.In addition,under the condition of 1 030 nm laser pumping,the net cooling effect cannot be observed in 7.5%Yb3+:YAG crystal.Therefore,for the radiation balance laser designed with Yb3+:YAG crystal as the gain medium,the doping concentration of Yb3+should not exceed 7.5%.关键词
