1. An apparatus for cutting out a human or animal tissue, said apparatus including a femtosecond laser configured to emit a laser beam in the form of pulses and a treatment device configured to produce a pattern in a focal plane from the laser beam generated by the femtosecond laser, the treatment device being positioned downstream from said femtosecond laser, wherein the treatment device comprises:
a spatial light modulator between the source and the focal plane, wherein said spatial light modulator is programmed using at least a phase mask configured to modulate the phase of the wavefront of the laser beam originating from the femtosecond laser so as to obtain a modulated laser beam,
an optical focusing system configured to focus the modulated laser beam in a cutting plane, and
a control unit configured to control the movement of the optical focusing system along an optical path of the laser beam to move the focal plane into at least three respective cutting planes so as to form a stack of tissue cutting surfaces.
