MATCHING LASER OPTICAL SYSTEM FOR ENSURING OUTPUT WAIST SIZE AND POSITION CONSTANCY Russian patent published in 2011 - IPC G02B27/09 

FIELD: physics.

SUBSTANCE: matching laser optical system is configured to ensure constancy of the size and position of the output waist during variation of the size of the input waist and comprises a laser, the beam of which, with a confocal parameter Z_k, has an initial waist with radius varying in the range [h_p,min; h_p,max] with nominal value h_p0, as well as an optical system consisting of first and second mobile components configured to form in the plane of the irradiated object, the output waist of the laser beam with constant size h_p and at a constant distance L from the initial waist.

EFFECT: ensuring constant size and position of the output waist relative the initial waist.
