Abstract
A light source for an imaging system. The light source includes a microresonator laser array having opposing mirrors arranged substantially parallel to one another. A laser gain medium is between the opposing mirrors. An array of microrefractive elements is arranged to stabilize the microresonator. A pump laser's output is shaped by a lens that directs it toward the micro-resonator laser array. An output lens directs a plurality of laser beams from the microresonator laser array to be incoherently combined at an object to be illuminated.
