What QS Lasers does

QS Lasers (legal entity UAB "QS Lasers") is a Vilnius, Lithuania-based privately held manufacturer founded in 2018 that designs and builds compact diode-pumped solid-state (DPSS) lasers producing sub-nanosecond and picosecond pulses. The company offers four product lines: MPL Series passively Q-switched lasers (250-800 ps, up to 3 mJ), APL Series actively Q-switched lasers (500-700 ps with sub-0.2 ns jitter), GSL Series gain-switched sub-100 ps lasers, and a Custom Lasers line for OEM-specific wavelengths and configurations. Core technical differentiators include patented compact resonator designs, air-cooled thermoelectric (TEC) architectures eliminating water cooling, harmonic generation for 532/355/266 nm outputs, and a >3 Gshot lifetime rating. The 14-person team brings over 35 years of combined DPSS laser experience and focuses on OEM-ready form factors optimized for high-volume integration.

The company serves three use-case segments: scientific and research institutions (LIBS, holography, MALDI, remote sensing), industrial OEMs integrating lasers into medical diagnostics, OLED repair, and process equipment, and analytical instrumentation manufacturers (LiDAR, Raman, supercontinuum). Revenue is generated exclusively through hardware sales of standard catalog lasers (with 100% pre-payment terms) and custom engineering services (up to 50% deposit, balance before shipment), with deferred NET 30 payment available on invoice. The go-to-market is direct: trade show participation (Laser World of Photonics Munich, Laser Korea via AYIN, AMACEE Brno), LinkedIn, and inbound website inquiries, supplemented by OEM integration partnerships and custom development collaborations. Standard pricing is opaque, all quotes are bespoke, and there are no software, subscription, or recurring revenue streams.
