Serving North America, RPMC Lasers offers a wide selection of distributed feedback lasers (DFB), including single emitter laser diodes, laser diode modules, and quantum cascade lasers (QCLs). Available in NIR, SWIR, and LWIR wavelengths, these single-mode DFB laser diodes offer a mode-hop-free tunable, single-frequency output and are available ...
The LDB-DFB-1550-50CW is a single frequency CW laser coupled with Polarization Maintaining fiber. Built with Distributed Feed-Back Grating (DFB) as cavity reflector, it provides a pure, single longitudinal mode, and extremely stable wavelength source. This laser diode is fabricated with Multiple Quantum Well (MQW) for excellent reliability and ...
28 wrz 2023 · Thorlabs' Distributed Feedback (DFB) Lasers are narrow-linewidth, single-frequency laser diodes that use a corrugated waveguide throughout the active region of the laser cavity (see SFL Guide tab). A DFB laser's periodic structure acts as a distributed reflector, providing optical feedback and wavelength selection for the diode.
