<title>Investigation of the possibility of creating a multichannel photodetector based on the avalanche MRS-structure</title>

Investigation results of the avalanche process in MRS-structure are given and the possibility of creating the multichannel avalanche photodetector based on such a structure for the one- dimensional hologram disk memory system is considered. The experimental sample of the photodetector has sensitivity approximately 104 A/W with wavelength (lambda) approximately equals 0.63 micrometers and response speed approximately 5 nsec.
