nLIGHT Inc (NASDAQ: LASR) is a high-power laser company that designs, manufactures, and sells semiconductor lasers, fiber lasers, fiber amplifiers, and beam combination and control systems. Revenue comes from direct product sales of laser components and systems integrated into customers' laser systems or manufacturing tools, as well as through its Advanced Development segment serving defense programs. The company sells into three primary end markets: Aerospace and Defense, Industrial, and Microfabrication. nLIGHT operates in two reportable segments, Laser Products and Advanced Development, with products spanning high-energy laser systems for directed energy applications, optical sensing, and advanced manufacturing. Vertical integration across the laser stack, from semiconductor laser diodes through complete fiber laser assemblies, is a stated design and cost advantage. The company trades on the Nasdaq Global Select Market under the ticker LASR.

Revenue model

Transactional product sales of high-power semiconductor lasers, fiber lasers, pulsed fiber lasers, fiber amplifiers, and beam combination and control systems. Products are sold directly to customers who integrate them into laser systems or manufacturing tools. The Advanced Development segment generates revenue through defense development programs and contracts.

Products and services

High-power semiconductor lasers, continuous wave (CW) and pulsed fiber lasers, fiber amplifiers, beam combination and control systems for high-energy laser (HEL) systems, directed energy systems, and laser sensing systems for defense applications.

Customers and end markets

Three primary end markets: Aerospace and Defense (directed energy, optical sensing, defense laser systems), Industrial (laser systems integration), and Microfabrication (advanced manufacturing tools). Customers are typically laser system integrators or manufacturers who incorporate nLIGHT products into their own systems.

Value-chain role

Component and subsystem supplier. nLIGHT sits upstream of laser system OEMs and defense prime contractors, supplying core laser sources and beam control hardware that are integrated into end-use systems by customers.
