Handheld laser system emitting visible and non-visible radiation

摘要

A laser system for use in medical, industrial, commercial or research applications in which the location and energy and power density of a nonvisible (e.g., infrared or ultraviolet) laser beam is defined by a plurality of visible beams. Collimating optics are used to direct both the nonvisible and visible beams on the target, such that when the visible beam is in focus on the target, the nonvisible beam has the optimum energy and power density. One implementation of the invention is a self-contained hand-held surgical laser that provides surgeons with the optimal laser beam parameters for laser tissue soldering.
