ABSTRACT OF THE DISCLOSURE This invention relates to a self-contained microsurgical laser which has a housing adapted for mounting on a surgical microscope. Mounted within the housing are an infrared laser source and a visible laser source. An interrupter, a polarizer and an attenuater are provided in the beam path of the infrared laser. Beam expanders are provided in the paths of both beams. Wave front correction lenses are provided in the path of the visible laser beam so that its focal point is coincident with the focal point of the infrared laser beam. The beam of the visible laser is superimposed onto the beam of the infrared laser. Power level detectors are provided. Manipulator mechanisms are provided for deflecting the combined laser beams in the X and Y directions in a plane perpendicular to the combined beams. The combined beams are focused onto a spot of less than 200 microns in diameter at the focal plane of the focusing means. This instrument can be used for repairing torn or severed body structure by exposing the surfaces to be joined to an infrared laser source for a period of time sufficient to effect the repair.
