William D Fountain, Carl F Knopp: System for scanning a surgical laser beam. Phoenix Laser Systems, Thomas M Freiburger, February 21, 1995: US05391165 (99 worldwide citation)

In a laser beam delivery system for a surgical laser beam, steering and scanning of the laser beam along the target in transverse (X and Y) directions is accomplished in a mechanically simple and fast-responding manner. Closely adjacent to the objective lens assembly of the delivery system is a pair ...

H Alfred Sklar, Alan M Frank: Spectral division of reflected light in complex optical diagnostic and therapeutic systems. Phoenix Laser Systems, Thomas M Freiburger, September 17, 1991: US05048946 (85 worldwide citation)

A diagnostic system for support of laser ocular surgery, for example, solves a problem of competition for light which is often encountered when a series of different detectors are used to receive and detect features of a target reflecting an illuminating light beam. The intensity of an illuminating ...
