A laser system for ophthalmic surgery includes a laser source to generate a pulsed laser beam, an XY scanner to receive the pulsed laser beam and to output an XY-scanning beam, scanned in two directions transverse to a Z direction, a Z scanner in a scanner housing to receive the XY-scanning beam and to output an XYZ-scanning beam scanned additionally in the Z direction, a mirror to deflect the XYZ-scanning beam received from the Z scanner, and an objective, in an objective housing, to receive the deflected XYZ-scanning beam and to focus the received XYZ-scanning beam onto a target region, wherein the scanner housing is separate from the objective housing.
