ABSTRACT:
An apparatus comprising a continuous wave (CW) laser and a transverse electrode atmospheric (TEA) pulsed laser, the continuous wave laser and transverse electrode atmospheric pulsed laser each producing laser beams, the laser beams from each of the lasers being provided to an optical mixer for combing the two laser beams into an output beam. The output beam can be either laser beam individually, or a combined coaxial beam wherein the CW laser beam and TEA pulsed laser beam are superimposed on each other. Preferably, the two lasers are CO.sub.2 lasers. The CW laser can also be operated in a pulsed mode. The device is particularly useful for medical and surgical treatment and provides effects not possible before.
