BEAM SCANNING LASER Russian patent published in 2013 - IPC H01S3/83 H01S3/101 

FIELD: physics.

SUBSTANCE: beam scanning laser has a laser radiation source, a resonator through one of the optical elements of which a scanning beam comes out, a laser radiation amplifier, light modulators, retarders and polarisation dividers inside the resonator, as well as at least one optical system which returns laser radiation reflected from one of the polarisation dividers into the resonator. The laser radiation source lies outside the resonator; the resonator is based on an annular scheme in which input of radiation from the radiation source and output of the scanning beam is provided through the polarisation dividers which also act as mirrors and the resonator; the optical system gives angular displacement of the laser radiation returned into the resonator, which is reflected from one of the polarisation dividers in the resonator.

EFFECT: high power and repetition frequency of laser beams.
