Abstract: A coupling interface between a laser source and a tissue to be treated, remarkable in that the coupling interface comprises:



a ring (3) including:

a double-walled partition (31),
a window (33) transparent to a laser beam generated by the laser source, said window being sealingly mounted on the distal end of the ring so as to close the distal end of the ring,


a gel block (4) intended to be positioned in a working housing of the ring.
