High-precision DFB distributed feedback laser for rail transit
Covering NIR to LWIR wavelengths (750nm–17µm), these lasers feature integrated DFB gratings and TEC cooling for robust thermal management and low-noise performance across diverse conditions. nanoplus sets the standard for DFB laser technology. The integration of a distributed grating on the semiconductor laser chip ensures continuous single-frequency operation as well as exceptional precision, stability and reliability. This is almost universally realized by putting a wavelength-dependent reflector into the laser cavity, in a distributed feedback laser. The mountain top of Kilimanjaro, like the cleaved.
