This single-wavelength laser is available in both standard and ultra-narrow models, reaching down to 0.08 kHz typical linewidth. Ultra-low phase noise and fast frequency modulation properties make this laser unique and sets new standards in single frequency lasers.

It integrates a DFB laser diode, a low noise current source and a temperature controller in a single, compact package. The ultra-narrow LXM-U also combines a frequency noise cancelation system that provides unmatched performance without compromising the lasing mode stability. This module represents a reliable and easy-to integrate laser source for OEM applications such as:

Distributed acoustic sensing based on Rayleigh Scattering (DAS / C-OTDR / φ-OTDR / OFDR)
Frequency modulation continuous wave (FMCW) lidar
Doppler lidar & vibrometry
Brillouin sensing
Quantum key distribution
Radio frequency over fiber
Precision metrology
