Up to Real-time
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.
HighFinesse LWA-100k series
The 100k models cover broad wavelength ranges and can be used to analyze narrow- and broadband laser sources within the NIR. Analysis tools like time resolved frequency deviations charts, frequency noise density spectra and lineshape representation enable detailed laser noise analysis.
HighFinesse LWA-1k series
The 1k models are ultimate high-end optical instruments engineered to analyze and control the frequency noise and lineshape of ultra-narrow lasers. Additionally these instruments offer the option to investigate the relative intensity noise of the laser light source with very high resolution and sensitivity.
