The U.S. Naval Sea Systems Command awarded a $425,000 firm-fixed-price purchase order to Lsense Inc., a for-profit manufacturer of laser and optical equipment, for a flashlamp-pumped erbium-doped yttrium aluminum garnet (Er:YAG) laser system and associated components. The laser system and mirrors are intended to support laser atmospheric propagation studies for the Naval Undersea Warfare Center Division Keyport. The award was a sole-source, non-competitive procurement under the North American Industry Classification System (NAICS) code for Optical Instrument and Lens Manufacturing, with no set-aside designation. Lsense has previously provided laser equipment, custom cables, telescopes, and other hardware to prime contractors supporting the Naval Air Warfare Center Weapons Division.
