【摘要】：为了实现低阈值光微流荧光共振能量转移(FRET)激光,基于制备的高品质因子、高稳定法布里-珀罗(F-P)微腔,采用间接抽运方法研究了两种F-P谐振腔中光微流FRET激光的产生。直接抽运施主染料,使得施主染料通过FRET的方式把能量传递给受主染料,从而实现受主染料的间接能量抽运。结果表明,在此种抽运方式下,F-P光微流激光腔中实现了0.48μJ/mm2的低激光抽运能量密度阈值;并可通过FRET激光产生的形式实现对低浓度物质的检测。
[Abstract]:In order to realize the low threshold photoluminescence resonance energy transfer (FRET) laser, a high stability Fabry-Perot (F-P) microcavity was prepared based on the high quality factor. The generation of two kinds of optical microflow FRET laser in F-P resonator is studied by indirect pumping method. The donor dye is pumped directly, which makes the donor dye transfer energy to the acceptor dye by FRET. The results show that the low laser pumping energy density threshold of 0.48 渭 J/mm2 is achieved in the F-P microflow laser cavity. The low concentration substance can be detected by FRET laser.
