HighFinesse

HighFinesse calibration sources are frequency stabilized, narrow linewidth laser sources suitable for different applications. With an absolute accuracy down to ±11 kHz, these fiber-coupled lasers feature extremely short warm-up time (< 2 min), have a compact design and are user friendly, plug and play devices. They are ideal for quick and accurate calibration of the complete series of HighFinesse wavemeters.

The grating based HighFinesse/ Ångstrom’ spectrometers offer the capability for a very accurate simultaneous measurement of both wavelength and linewidth of laser sources. With a resolving power up to 40000 and a measurement speed up to 500 MHz, the product series covers the range from 192 nm to 11000 nm, allowing measurements of both pulsed and cw lasers. The grating based technology enables the analysis of laser sources over a large linewidth range. Connected to the PC via USB, after a simple software installation the spectrometers are ready for use.

Our sensitive and compact, HighFinesse/Ångstrom’ wavelength meters deliver high speed wavelength measurements of pulsed and continuous laser with absolute accuracy down to 2 MHz. A wide variety of models is available, covering wavelength ranges from 192 nm up to 11000 nm. The devices can not only accurately measure wavelengths, but can with their output used to stabilize a laser such that its emission wavelength remains very stable.

To fully meet the increasing demand of flexibility and integration of laser test equipment, the HighFinesse world famous WS wavemeters are available as rack and standalone systems. The latter do not require an external computer. They can be controlled locally by connecting screen, keyboard, mouse or via touch screen (not available for all models) and using Ethernet connection via the DLL-based API or SCPI commands.

HighFinesse offers various kinds of devices for testing lasers:

• sensitive and compact HighFinesse/Ångstrom’ wavelength meters for high speed wavelength measurements
• HighFinesse linewidth analyzers for measuring laser linewidths
• grating based HighFinesse/ Ångstrom’ spectrometers for very accurate simultaneous measurement of both wavelength and linewidth of laser sources

HighFinesse linewidth analyzers are the ultimate high-end instruments for measuring, analyzing and controlling frequency, linewidth and intensity noise of laser light sources. The product series covers a measurement range from 450 nm up to 1625 nm and enables the analysis of both very narrow laser lines down to 1 kHz as well as broader spectra up to 100 MHz. Thanks to the included software, the instrument delivers real-time analysis, with no need for further calculation. The analyzers feature an extremely high resolution and accuracy and are ideal for optimizing the stability of laser setups.
