The Spectra-Physics® Matisse® C is a fully automated and compact single frequency tunable ring laser that is ideal for Quantum and AMO (atomic, molecular and optical physics) applications. The Matisse C system has the industry’s highest output power, the narrowest external linewidth, and the broadest mode-hop-free tuning range. The compact, sealed, and fully automated design with broadband mirrors and specially developed optical mounts provide long term stability and worry free operation.

The Matisse C is fully automated for truly hands free operation. The laser is controlled with an intuitive GUI for quick and easy wavelength selection, piezo scanning, and frequency locking. It is housed in a compact closed box with no external adjustment knobs. An automated alignment optimization routine utilizes picomotors to seamlessly optimize the system for peak performance. Broadband coated mirrors enable hands-free tuning across 668–1068 nm, eliminating the need to manually change optics sets.
Broadband optics provides unprecedented 668–1068 nm automated continuous tuning. Coupled with the Millennia® eV™ 25 pump laser, the Matisse C produces >7.2 W of output power. The Matisse C provides more than 400 nm of tuning with automated optics set switching and linewidths down to 20 kHz, with fully integrated PDH lock to X reference cell.
A unique phase lock loop technique provides <100 kHz linewidth with passive frequency stabilization. The Matisse CR can be readily upgraded to the higher resolution Matisse CS.
The Matisse CS actively-stabilized Ti:Sapphire ring laser utilizes a reference cavity and offers a spectral linewidth of <35 kHz.
The Matisse CX provides spectral linewidths below 20 kHz. This ultra-narrow linewidth is achieved by use of an intra-cavity electro-optic modulator (EOM) and the Pound-Drever-Hall stabilization scheme with a high finesse external reference cavity.
Noise contributions to linewidth occur on different timescales: seconds correspond to thermal drifts, tens to hundreds of milliseconds correspond to acoustic noise and vibrations, and microseconds correspond to electrical noise. Linewidth measurements for the Matisse C are provided for 100 milliseconds and 100 microsecond intervals. The 100 millisecond measurement fully accounts for electrical and vibrational noise contributions and showcases the exceptional engineering of the Matisse laser platform.
Superior mechanical stability, specially designed optical mounts, unique tuning methods, and the preferred Out of Plane cavity design of the Matisse C all contribute to the exceptional mode-hop-free scanning range of >50 GHz. In order to take this to the next level, we have developed Scan Stitching for wide mode-hop-free tuning over the full wavelength range (up to 400 nm.) The fully automated Scan Stitching function is easily activated through the Matisse C GUI.
The Matisse is featured with a Dynamic Scan Range function for easy adjustment of the wavelength tuning resolution. This is achieved via a built in switchable piezo amplifier with easy software control. Tuning resolutions down to 50 kHz can be selected when fine wavelength adjustments are needed.
CW single frequency ring lasers utilize a Phase Lock Loop (PLL) in order to stabilize the laser cavity to a single longitudinal mode. The Matisse C incorporates a unique PLL technique that delivers low dither frequencies (down to 500 Hz) to minimize laser noise and allows easy adjustability of the frequency (500 Hz – 3 kHz) via software.
To verify and analyze the output power of your Matisse C laser, we recommend the Ophir 10A (above 3 W output power) thermal power sensor and Centauri laser power meter. Additional information on this laser measurement equipment can be found on the ophiropt.com website. Other Ophir sensors and meters may also be suitable for the Matisse C, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
