LWA-100k

High Resolution Lineshape Analyzer

For narrow and broadband spectra of various lasers.

The HighFinesse Linewidth Analyzers of the LWA-100k series are specialized high-end devices for measuring and analyzing highly resolved lineshape and frequency noise spectra of narrow- and broadband lasers.

A combination of two interferometric based measurement modes and specifically tailored optics and electronics enable the LWA-100k to quickly acquire various information about the laser source.

The LWA is perfectly suited for laser development and adjustment. In combination with a HighFinesse wavemeter high resolution classification of lasers and laser systems can be performed.

Main benefits and properties:
  • Large wavelength intervals in the visible and near-infrared regime
  • Measureable combined linewidths range from 100 kHz– 300 MHz
  • Intrinsic linewidths down to 20 kHz
  • Spectral lineshape and frequency noise analysis
  • High sample rate of 30 MS/s
  • High linewidth accuracy down to 20 kHz
  • No reference source required
