CUTTING APPARATUS WITH OPTICAL CONNECTOR AND POLARIZATION CORRECTOR Russian patent published in 2024 - IPC A61B18/20 A61F9/08 

FIELD: medicine.

SUBSTANCE: apparatus for cutting human or animal tissue, such as a cornea or lens, comprises: a femtosecond laser source for emitting an initial laser beam in the form of pulses, a shaping system located at the output of the femtosecond laser, to convert the initial laser beam into a phase-modulated single laser beam, an optical connector between the laser source and the shaping system, wherein optical connector includes optical fibre, a polarization corrector for changing the polarization of the initial laser beam at the input end of the optical connector so that the polarization of the laser beam at the output end of the optical connector corresponds to a given reference polarization. Therapeutic device for use in cutting a cornea or lens, comprising a cutting apparatus.

EFFECT: preservation of power of the modulated laser beam.
