| 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. |
