Koheras Narrow linewidth Low Noise Fiber Lasers

The Koheras™ fiber lasers are ultra low noise sources with longitudinal single mode and single frequency operation. The lasers are based on a DFB design ensuring robust and reliable operation, and are delivered as fully integrated systems for the industry and scientific community.  They offer an unprecedented low phase and intensity noise level, very high stability and mode-hop free inherent single frequency output - both under stable and uneven environmental conditions. Furthermore, shot noise limited solutions are available for applications demanding a very low intensity noise level.

Koheras fiber lasers are available within a wide range of wavelengths in the 1 and 1.5 micron wavelength range, and with output power levels from 10 mW to 15 W. The systems offer several control and monitor options with either direct access from the front panel or via a PC using the GraphiK program.

Applications include oil & gas sensingpipeline monitoringwind Doppler LIDARphoton Doppler velocimetry (PDV), spectroscopy, and basic research. NKT Photonics offers a service package with extended warranty and remote monitoring/support for all its products.
