FIELD: physics, optics.
SUBSTANCE: group of inventions relates to medicine. A laser system for ophthalmic surgery, comprising: laser radiation source for generating a pulsed laser beam, an XY scanner for receiving the pulsed laser beam and for emitting an XY scanning beam in two directions across the Z axis, a Z scanner for receiving the XY scanning laser beam and for emitting an XYZ scanning beam additionally across the Z axis, wherein the Z scanner comprises a first group of lenses for emitting a beam having an intermediate focal plane and a group of movable lens for receiving the beam through the intermediate focal plane and for collimating the beam in a variable manner, and an objective lens for receiving the collimated beam from the Z scanner and for focusing the beam into a focal spot in a target region.
EFFECT: use of the present group of inventions enables to minimise optical distortion of the laser beam during scanning and focusing the laser beam in eyes.
