Abstract
A hair removal device and single-emitter diode based light homogenizing apparatus for use therewith, the homogenizing apparatus including a light guide having oppositely tapered walls, and a plurality of single-emitter laser diodes mounted to a carrier plate and optically coupled to an input end of the light guide. The housing of the device has an arcuate and ergonomic shape so as to be capable of being gripped by a user. A diffuser is applied to an output window of the device in order to produce a safe divergence of light exiting the device. Beams emitted from the diodes and coupled into the light guide are totally internally reflected to enhance the uniformity of the output beam exiting the light guide.
