Abstract: A miniaturized multi-functional laser resonator (10). The novel invention includes a mobile optical bench (100), a predetermined number of laser sources (34, 50, 54, 58) mounted to the optical bench (100), and a plurality of optical elements (80) for combining laser beams output from the laser sources such that the beams converge on a small area, such as a telescope (20). The invention further includes a mechanism (102) for aligning the laser beams. In the illustrative embodiment, the mechanism for aligning the beams includes v-grooved mounting surfaces (102) formed in the optical bench (100). The optical elements (80) are mounted in the v-grooved surfaces (102) of the optical bench (100) such that the laser beams are aligned. In the illustrative embodiment, the invention includes four laser diodes generating 1053 nM, 905 nM, 850 nM, and 650 nM laser beams.
