【摘要】 分别利用氩离子激光,二倍频YAG∶Nd激光泵浦的诺明6G可调谐窄线宽(0.5 cm-1)染料激光和899-21可调谐染料激光作为光源,以单色仪-锁相放大器-光电倍增管-计算机数据采集系统记录光谱,对Y2SiO5∶Eu3+晶体进行了光谱和光谱烧孔研究。在常温和液氮温度下测量了晶体的激发光谱、荧光光谱等。在16 K温度下对晶体进行了光谱烧孔研究,得到了孔宽约80 MHz并能保存10 h的永久性光谱孔。

【Abstract】 By using an Ar+ ion laser,a tunable Rh6G dye laser(linewidth: 0.5 cm-1) pumped by the second harmonic of a YAG∶Nd laser and an 899-21 dye laser as light sources and using a monochromator,a phase-locking amplifier and a computer as the data detecting system,the spectra and spectral hole burning of Eu3+∶Y2SiO5 crystal were researched in this paper.Photoluminescence excitation spectrum and site selective fluorescence spectrum were detected at room temperature and 77 K.Hole burning experiments were reached at 16 K.A spectral hole with hole width of about 80 MHz were detected and it could be kept for 10 h.
