5 September 2002 Application of YAG laser in photoelectron action measurement
Author Affiliations +
A YAG super short pulse laser (355nm, 35ps) is used as an exposure source. The free photoelectron lifetime and decay process of silver halide crystals could be measured and analyzed by the microwave dielectric spectrum detection equipment (MWA). This is a powerful tool that could quickly detect the change of dielectric function of AgX microcrystal. This technology enables measurement of the free photoelectron and shallow trapped electron decay process simultaneously that decide the sensitivity and other efficiency of silver halide material.
