  • Laser system and its method of use
    Patent number: 4396285
    Abstract: A laser system for medical applications has at least two lasers and a movable concave reflector. The lasers are capable of generating beams of coherent electromagnetic radiation. One of the beams, an aiming beam, is aligned to impinge the reflector, to reflect therefrom and to impinge a biological specimen. The reflector is moved until the beam is aligned to impinge the desired position. The reflector is held stationary and the second beam is generated. The second beam is also aligned to impinge the reflector to reflect therefrom and to impinge the same desired position as that impinged by the first beam.
