PS-NLL Narrow Linewidth Laser
PS-NLL

The PureSpectrum™-NLL/NLL-E Narrow Linewidth Laser is a compact, wavelength stabilized, ultra-low-noise and narrow-linewidth DFB semiconductor laser module. Its high wavelength stability optimizes the performance of laser-based sensing systems in applications such as:

  • Distributed acoustic sensing
  • Coherent OTDR
  • Oil and Gas - interferometric, phase shift applications: seismic/pressure/Brillouin temperature and strain
  • LIDAR systems

Features

  • Wavelength stability +/- 1.5 pm over 10 days
  • Linewidth < 5 kHz
  • Long coherence length laser
  • Output power up to 80 mW
