Abstract
A light engine includes multiple laser diodes, each configured to emit laser light, and a light source unit having multiple channels, each of the channels is associated with one of the laser diodes and configured to transmit the laser light emitted from the corresponding laser diode. The channels may be, for example, fiber optic strands or optical pathways within a channeled lightguide. The light engine further includes a ferrule coupled to the light source unit and configured to receive the laser light from the light source unit and to output a collimated beam of laser light comprising each wavelength of laser light emitted by the laser diodes.
