DEVICE FOR FOCUSING LASER RADIATION ON AN OBJECT Russian patent published in 2007 - IPC H04B10/10 

FIELD: laser engineering , possible use as focusing system for powerful laser radiation during creation of technological laser complexes.

SUBSTANCE: device contains generating optical system, photo-receiving device, focus correction system, optical compensation block, radiation source. Generating optical system consists of receiving and transferring telescopes. Transferring telescope is optically conjugated with radiation source. Receiving telescope is optically conjugated with optical compensation block. Optical compensation block is optically conjugated with photo-receiving system. Photo-receiving system outlet is connected to input of focus correction system. First output of focus correction system is connected to optical compensation block drives. Second output of focus correction system is connected to drive of deflecting plate of radiation source. Inputs of drives for horizontal and vertical guidance of generating optical system are connected to focus correction system.

EFFECT: increased efficiency of laser radiation focusing due to increased energy density at given potions of moveable or inaccessible technological object.
