Computer Render of a Multibeam, Multi-functional Laser

Caption

This is a computer rendering of one of the prototype multibeam, multi-functional lasers demonstrated by the team. The new laser emits several highly directional beams with the same wavelength near 8 microns, which requires two coherent beams: a probe beam and a reference beam. The probe beam interacts with a sample and recombines with the reference beam to reveal optical properties of the sample. A second type laser emits multiple small divergence beams with different wavelengths (9.3 and 10.5 microns) into different directions.
