摘要

在经过标定的Nd:YAG激光器产生的超短红外脉冲激光激励下,采用双光束入射、单脉冲测量方案,利用可见光条纹相机研究了电子俘获材料CaS:Eu,Sm的红外上转换发光情况,结果表明:在λ=1.064 μm,FWHM=19.2 ps的红外脉冲激光作用下,这类材料红外上转换发光的FWHM优于14.3 ps。

Abstract

By projecting double pulses on the photocathode of a streak camera, the optically stimulated luminescence (OSL) from electron trapping materials such as CaS:Eu, and Sm, stimulated with a single 19.2 ps pulse (FWHM), is shown to occur with response and decays within less than 14.3 ps (FWHM). The two phosphors investigated are efficiently stimulated with 1.064 μm photons from a pulsed Nd:yttrium aluminum garnet (YAG) laser. By analysing and discussing the result, it is shown that this kind of novel materials may be used in the rapid infrared up-conversion and related fields.
