The use of silicon alloyed with gold, to determine the shape of the optical signal

In the article the results of numerical investigations of photoconductivity kinetics under the excitation of semiconductor by high-frequency pulses of arbitrary-shaped light are presented. The kinetics of photoconductivity under the conditions $\tau _{j} \omega >>1$ is determined by the dependency of the value of the generate rate on time. It does not depend on the lifetimes of electrons and holes. It allows to reconstruct the time waveform of high-frequency pulse of light
