Where to Buy Laser Stabilization Devices

The optical frequency discriminator (OFD) system of SILENTSYS smartly delivers a voltage signal that is proportional to the excursions of optical frequency of the input laser beam. This turn-key module is suitable for laser frequency noise characterization and/or for laser frequency stabilization to drastically reduced its optical full width at half maximum linewidth. The OFD features ultralow noise performances being successful in achieving frequency noise level as low as 0.1 Hz²/Hz with >60 dB noise reduction; and that is achieved in a compact and user-friendly package.

This product is available in a huge wavelength range from UV, VIS to NIR, with one or two optical modules inside to be a very versatil tool.

Enhance your laser with simplicity!

Menlo Systems offers ultrastable, frequency stabilized lasers at basically any wavelength. We supply fully characterized systems with linewidths <1 Hz and Allan deviations of 2 × 10⁻¹⁵ (in 1 s) as well as modules and components allowing for state-of-the-art systems tailored to your requirements.

TOPTICA’s unique CHARM technology (Coherence-advanced regulation method) provides an active stabilization of the laser’s coherence. An integral feature of the TopMode laser family, this scheme ensures excellent long-term stability of the lasing wavelength and output power, as well as an extremely low intensity noise.

The D2-125 reconfigurable servo offers a full PI2D loop filter transfer function with 10 MHz of control bandwidth. Tightly lock your laser to a variety of error signals.

The D2-135 Offset Phase Lock Servo will phase lock a slave to a master laser and allow for a user-specified frequency offset between 250 MHz and >9.3 GHz.

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.
