450-2200nm Tunable Laser Single Mode Fiber Coupled

SKU: SUTL

The SUTL is a fiber-coupled, single-mode tunable laser delivering up to 0.5 mW per 0.7 nm linewidth peak with more than 5 W of average power across an ultra-broad spectral range of 450–2200 nm. It offers power stability (<0.5% RMS) and is based on a supercontinuum laser platform operating at repetition rates up to 4 MHz. Wavelength tunability is achieved via a fiber-optic tunable filter providing a typical 200 nm tuning range, extendable using multiple filters. The single-mode output exhibits minimal polarization dependence, while the polarization-maintaining (PM) configuration delivers highly stable polarized light with an extinction ratio up to 35 dB. The standard configuration provides free-space output through a photonic crystal fiber (PCF) terminated with a fused glass core endface to prevent damage. Because the PCF mode field differs significantly from conventional fibers, direct connectorized coupling typically incurs losses exceeding 10 dB. To address this, mode-field-adapter splicing is available with various fiber types to maintain single mode characters with standard connectors for convenient integration. Optional output isolators ensure operational stability in systems subject to back-reflections. The SUTL is offered as a turnkey, plug-and-play benchtop system ideal for scientific and industrial.
