Abstract
The response and decay time of the optically stimulated luminescence of electron trapping material CaS:Eu,Sm to ultrashort infrared pulse has been measured by projecting two 1.064 μm laser pulses on the photocathode of a streak camera, one illuminates ETM screen on the photocathode, another illuminates the photocathode after a frequency doubling. The result indicates that the response and decay time is less than 14.3 ps. The decay law of the infrared upconversion luminescence followed by CaS:Eu,Sm is also presented. The work shows that this kind of electron trapping materials could be widely used in the rapid infrared upconversion and detection.
