Up to Real-time
Analysis

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.

Analyzing Narrow- and Broadband Lasers

HighFinesse Linewidth Analyzer LWA-100k

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 Linewidth Analyzer LWA-1k

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.

Analyzing Options

Frequency deviation time trace and histogram

Frequency noise density spectrum

Intensity noise spectrum

Laser lineshape spectrum

Evaluation Options
