Electroabsorption in high-power photoconductive switches

摘要: Photoconductive semiconductor switches are useful for the generation of high voltage electrical pulses with picosecond rise times. In addition, availability power laser arrays allows elimination large flash-lamp pumped solid state lasers. this paper, role electro-absorption is investigated. A theoretical model has been formulated which combines measured field and wavelength dependent absorption data a one dimensional drift diffusion model. The results indicate existence optimum parameters both pump intensity before plateau diminishing returns achieved. along detailed explanation formalism is included in paper.
