THE INVENTION RELATES TO MEDICINE, NAMELY, TO OPHTHALMOLOGY. THE DEVICE OF THE INVENTION COMPRISES AN EXCIMER PULSED LASER (1) AND A DENSITY DISTRIBUTOR (3) OF LASER RADIATION ENERGY OVER THE CROSS- SECTION AREA OF A LASER BEAM (2). ACCORDING TO THE INVENTION, THE DENSITY DISTRIBUTOR (3) IS MADE AS AN OPTIC CELL (7) WHOSE OPTICAL WINDOWS (8,9) ARE TRANSPARENT TO LASER RADIATION AND THE INNER SURFACE OF AT LEAST ONE OF THEM IS SHAPED AS A SECOND- ORDER SURFACE OF REVOLUTION WHOSE AXIS OF ROTATION ALIGNS WITH AN AXIS (21) OF SYMMETRY OF THE LASER BEAM (2). THE OPTIC CELL (7) IS FILLED WITH A FLUID MEDIUM (10) CAPABLE OF PARTIALLY ABSORBING LASER RADIATION. A LASER BEAM (31) AT THE OUTLET OF THE DENSITY DISTRIBUTOR (3) FEATURES APPROXIMATELY PARABOLIC ENERGY DISTRIBUTION OVER THE CROSS- SECTION AREA HAVING ITS MAXIMUM AT THE CENTER OR THE PERIPHERY.(FIG. 1)
