A coherent light source system is presented. The system comprises at least one coherent light emitter producing a coherent light beam, a focusing lens unit, and a beam shaper unit, the beam shaper unit being accommodated between the coherent light emitter and the collimating lens unit being in a front focal plane of the focusing lens unit, thereby providing a substantially uniform profile and high-degree collimation at a desired plane in an optical path of light propagation.
