QTekLaser™ FAQ

Company Overview

QTEKLASER, LLC is a global supplier of precision-engineered fiber‑laser systems, headquartered in Waltham, MA, USA.
We design and manufacture advanced fiber‑laser solutions for applications spanning quantum computing, atomic physics, scientific instrumentation, and industrial testing.
Laser systems deliver narrow-linewidth, polarization-maintaining (PM) outputs across 260–2040 nm, with output powers up to 100 W.
High reliability is achieved via all-fiber design, free from stimulated Brillouin scattering (SBS), low noise, excellent power stability, low thermal lensing, and superior beam quality.
Systems feature user-friendly interfaces with IoT-enabled control, housed in industrial 3U or 4U 19″ rack-mount chassis.
