Sweeping optical scanner of an apparatus for cutting-out a human or animal tissue

An apparatus configured to cut a human or animal tissue, wherein said apparatus includes:

• a femtosecond laser configured to send a laser beam in the form of pulses, and
• a treatment device adapted for treating the laser beam generated by the femtosecond laser, the treatment device being positioned downstream from said femtosecond laser, the treatment device comprising:
• a shaping system positioned on the trajectory of said laser beam, said shaping system including a spatial light modulator configured to display a phase modulation set value and produce a phase—modulated laser single-beam by modulating the phase of the wave front of the laser beam generated by the femtosecond laser,
• control means configured to apply the phase modulation set value to the shaping system, wherein the phase modulation set value is calculated by the control means for distributing the energy of the phase—modulated laser single-beam in at least two impact points forming a pattern in a focal plane of said phase—modulated laser single-beam, wherein each impact point generates a cavitation bubble within the human or animal tissue, and wherein an intensity of each impact point will be attenuated at a same time if any portion of the phase-modulated laser single-beam is lost along a propagation path of the phase-modulated laser single beam,
• an optical focusing system downstream from the shaping system, the optical focusing system comprising a concentrator module configured to focus the phase—modulated laser single-beam in the focal plane and a depth—positioning module configured to displace the focal plane into a plurality of cutting-out planes, and
• a sweeping optical scanner positioned between the concentrator module and the depth—positioning module, said sweeping optical scanner being configured to displace the pattern in the focal plane in a plurality of positions.
