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。
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 Eu^3+ :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.
