A system comprising a multiplicity of quantum dot lasers disposed on a back surface of a control circuit, wherein each of the quantum dot lasers produces coherent light; a multiplicity of micro-lens collimators, each micro-lens collimator secured to a corresponding quantum dot laser, where light generated by the quantum dot laser passes through the fiber and exits at the tip; a diffraction grating, wherein the light from each of the micro-lens collimators is directed to the diffraction grating; and wherein the coherent light leaving the diffraction grating is a high powered optical light. |
