Multi channel fiber laser
AcoustiK™ NKT Photonics

Koheras AcoustiK™ System is an 8 channel narrow linewidth fiber laser system for multiplexed sensor interrogation systems based on truly single mode, single frequency DFB (Distributed-Feedback) Fiber Lasers with extremely high frequency stability and low phase and intensity noise. It is supplied with Koheras GraphiK™ software for the control and read-out of numerous laser parameters on a pc such as wavelength, output power, and RIN suppression.

Any interferometric use that requires high frequency stability or a long coherence length will benefit from this type of laser technology. The typical applications include seismic sensing such as oil and gas exploration and exploitation, security (perimeter and pipeline detection), and structural health monitoring.
