The HighFinesse Linewidth Analyzers are high-end optical instruments for measuring, analyzing and controlling frequency and intensity noise of laser light sources. By combining an interferometric working principle with ultra-low noise electronics, a superb sensitivity is achieved. The real-time signal output offers the option for a fast feedback loop that can be used to actively reduce the frequency noise of the laser.
