COMPACT ULTRA-NARROW LINEWIDTH
Ti:SAPPHIRE TUNABLE RING LASER
- Compact, sealed, fully automated design
- Hands free operation
- Broad tuning range (>300 nm) with one optics set
- Widest mode-hop-free piezo tuning >50 GHz
The Spectra-Physics® Matisse® C is a fully automated and compact single frequency ultra-stable, Out of Plane tunable ring laser. 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 truly hands free operation.
Coupled with the Millennia® eV™ pump laser, the Matisse C produces up to 6.5 W of output power. The Matisse C provides more than 300 nm of tuning with one optics set and linewidths down to 30 kHz.
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. Broadband coated mirrors enable uninterrupted tuning across 700–1000 nm while eliminating the need to change optics sets.
High Power and Broad Tuning
Broadband optics provides 700–1000 nm automated continuous tuning. Other wavelength options are available for higher power at specific wavelength ranges between 670 nm and 1038 nm. In addition, custom mirrors are available for specific wavelengths, such as 2 W at 671 nm, for unique experimental needs.
A unique phase lock loop technique provides <2 MHz 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 <50 kHz.
The Matisse CX provides spectral linewidths to below 20 kHz. This ultra-narrow linewidth is achieved by use of an intra-cavity electrooptic 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. Linewidths of the Matisse C are measured over 100 milliseconds, capturing both electrical and mechanical noise contributions and showcasing the exceptional mechanical 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 300 nm.) The fully automated Scan Stitching function is easily activated through the Matisse C GUI.
Dynamic Scan Range
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.
Variable Low Frequency Locking
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.
