Abstract
A multicolor laser source includes a collimator lens having first and second lens portions, a first laser unit for emitting light of a first color, a second laser unit for emitting light of a second color, a reflective unit disposed obliquely to a light-entrance axis of the first lens portion, a reflective diffusing member, and a lens array disposed on a light-exit axis of the second lens portion. The reflective unit is disposed opposite to the first and second laser units for reflecting the first and second color lights to the first lens portion along the light-entrance axis. The reflective diffusing member is disposed at a side of the collimator lens to homogenize the first and second laser lights and reflect the first and second color lights to the second lens portion along the first light-exit axis, to be outputted through the lens array.
