OPTICAL SYSTEM FOR GENERATION AND GUIDANCE OF LASER RADIATION Russian patent published in 2019 - IPC G01S17/88 F41G3/22 

FIELD: optics.

SUBSTANCE: invention can be used for delivery of powerful radiation to air and space objects and in laser location guidance systems. Optical system includes scanning device, transmitting laser module with fiber-optic output, a focusing unit comprising a collimating aspherical lens with a movement mechanism thereof along an optical axis, the main optical axis of which is perpendicular to the plane of the end of the fiber-optic output core and passes through its center, located in the focal point of the aspherical lens, a convex secondary parabolic mirror whose optical axis coincides with the main optical axis of the aspherical lens and is parallel or coincides with the optical axis of its full parabola spaced from the main optical axis of the aspherical lens at a distance h, concave main parabolic mirror with focus F, through geometric center of which passes its optical axis parallel or coinciding with optical axis of its full parabola. Focus f of the secondary mirror coincides with the focus F and their optical axes of the complete parabolas coincide. Secondary mirror is structurally connected to the scanning device. Characteristic size of the aperture of the main mirror is evaluated from the given ratio.

EFFECT: design of a compact optical system which forms a low-divergent beam of beams, high accuracy of adjustment, broader functional capabilities.
