PANCRATIC FOCUSING SYSTEM Russian patent published in 2014 - IPC G02B27/16 H01S3/23 B23K26/67 

FIELD: physics, optics.

SUBSTANCE: invention can be used in making high-power laser systems for focusing radiation at remote targets. The system includes a first lens, the first and second lens components of which are capable of moving along the optical axis of the lens. A third lens component is immovably mounted. The system includes an additional laser and at least one additional lens, which is identical to the first, arranged such that optical axes of the laser and all lenses cross at one point. The distances from the optical axis of the laser to optical axes of the lenses are equal. Each lens further includes a plane-parallel plate placed in front of the first component such that it is able to turn about an axis perpendicular to the meridian plane of the system. All optical components of the lenses are made of quartz glass. The plane-parallel plates, first and second lens components are kinematically synchronised with each other.

EFFECT: high accuracy of adjusting parameters of laser radiation at a target while simultaneously increasing the transmitted radiation power, high reliability and broader technical capabilities.
