Abstract
A high power light source having an array, bundle or separate plurality of laser diodes coupled to a same number of multimode waveguides to collect beams of light emitted from the of laser diodes is provided. An optical combiner receives the beams of light and combines the beams of light into a single forward propagating beam of light so that substantially all optical radiation within each beam of light overlaps the optical radiation each other beam to form the single beam. A reflective element is located to receive the single forward propagating beam of light and transmits greater than 60% of the single forward propagating beam of light therethrough. The reflective element reflects between 3–40% of the single forward propagating beam back to the laser diodes as feedback to stabilize said laser diodes.
