Omni Sciences, Inc. (OSI) is developing the most cost-effective and robust near- and mid-infrared, super-continuum fiber lasers in the world. OSI's patented super-continuum technology can generate continuous light over the near-IR, 0.8-2 microns, as well as mid-IR, 2-5 microns, with high output powers. Our laser technology is a practical super-continuum source that uses commercial off-the-shelf laser diodes and fibers (i.e., no optical bench) that covers several octaves of near-IR and mid-IR spectrum. This super-continuum source is unique in that a mode-locked laser is not required and only short fiber lengths are used. The spectral radiance is more than six orders-of-magnitude brighter than a typical lamp.

Listed below are archival journal papers that Omni Sciences has co-authored.
