Koheras AcoustiKT 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 GraphiKT software for the control and read-out of numerous laser parameters on a pc such as wavelength, output power, and RIN suppression.
