ABSTRACT:
The present invention teaches a diode laser system which utilizes optical fibers arranged in bundles whereby one group is bundled in a central section and one or more groups are arranged in a concentric circle or other symmetrical shape or configuration around the central bundle. Variable power ranges and power densities are transmitted from the different groups as required for a particular medical or industrial application. The effect is to deliver a focused output of power density in the desired range. Alternatively, the diode laser system can use sets of lenses, prisms, other optical elements to focus output from groups of diode laser emitters to a treatment site or treatment optical fiber as required for a particular medical or industrial application. The diode laser system may also be programmed to utilize varying bundles of fibers for less than maximum power output so as to maximize the overall usable lifetime of the system.
