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.

1. A laser system for ophthalmic surgery, comprising; a laser source, to generate a pulsed laser beam;a first Z scanner, to receive the pulsed laser beam, andto output a Z-scanning beam, scanned over a first Z scanning range,an XY scanner, to receive the pulsed laser beam from the first Z scanner, a
1. A laser system for ophthalmic surgery, comprising; a laser source, to generate a pulsed laser beam;a first Z scanner, to receive the pulsed laser beam, andto output a Z-scanning beam, scanned over a first Z scanning range,an XY scanner, to receive the pulsed laser beam from the first Z scanner, andto output an XY-scanning beam, scanned in two directions transverse to a Z direction;a second Z scanner in a scanner housing, to receive the XY-scanning beam, andto output an XYZ-scanning beam, scanned additionally in the Z direction over a second Z scanning range;a mirror, to deflect the XYZ-scanning beam received from the Z scanner; andan objective, in an objective housing, to receive the deflected XYZ-scanning beam; andto focus the received XYZ-scanning beam onto a target region, whereinthe scanner housing is separate from the objective housing. 2. The laser system of claim 1, wherein: the scanner housing is separate from the objective housing at least one of mechanically and functionally. 3. The laser system of claim 1, wherein the second Z scanner comprises: a first beam expander block; anda movable beam scanner, wherein the first beam expander block can be one of a fixed block and a movable block. 4. The laser system of claim 1, wherein: the second Z scanning range is between 5 mm to 10 mm. 5. The laser system of claim 1, wherein: the second Z scanning range is between 0 mm to 15 mm. 6. The ophthalmic laser system of claim 1, wherein the second Z scanner is configured to reduce the numerical aperture as the focal depth is increased.
