DEVICE FOR STABILISING TELE-ORIENTATION LASER SYSTEM Russian patent published in 2010 - IPC H04B10/10 

FIELD: physics; optics.

SUBSTANCE: invention relates to laser engineering and can be used for creating an information field of laser systems for tele-orientation and navigation and optical communication. For this purpose the device for stabilising the tele-orientation laser system includes: a laser, a two-dimensional acoustooptic deflector which includes two anisotropic acoustooptic cells, a polarisation light-splitting unit with a mirror end face, placed between the two-dimensional acoustooptic deflector and a third anisotropic acoustooptic cell, a wave plate (λ/2) and a polarisation optical splitter of laser radiation placed between the third anisotropic acoustooptic cell and a telescope, as well as two pairs of optical wedges, one of which is placed after the polarisation optical splitter of laser radiation and the other after the polarisation light-splitting unit, a telescopic system and a position-sensitive photodetector.

EFFECT: increased stability of operation of the tele-orientation laser system under external effects (temperature change, vibration).
