Features of modulation of high-power laser radiation for optical space control systems

In this work we justify the necessity of using shutter-type modulators to create laser radiation with the required parameters in fiber-optic systems.This is necessary to detect the fact of making changes in the optical system (unauthorized connection with the restoration of the function of communication channels). We have developed a shutter-type optical radiation modulator design. This modulator design has no fundamental limitations on the power of laser radiation, which is used to solve various problems. The investigation results of different work regime to the modulator are presented.
