Matisse® 2

ULTRA-NARROW LINEWIDTH TUNABLE RING LASER

  • Highest output power available >7.2 W
  • Narrowest linewidth <30 kHz rms
  • Field-upgradeable to dye or Ti:Sapphire gain medium
  • Widest mode-hop-free Diezo tuning of 50 GHz
  • Dust-sealed housing and massive steel baseplate

The Spectra-Physics® Matisse® 2 series is a family of state-of-the-art single frequency ultra-stable, narrow linewidth tunable ring lasers that are ideal for Quantum and AMO (atomic, molecular and optical physics) applications. The Matisse 2 system has the industry’s highest output power, the narrowest external linewidth, the broadest tuning range, and the most flexible architecture.

Coupled with the Millennia® eV™ 25 pump laser, the Matisse 2 produces over 7.2 W of output power. With flexibility to be configured for either Ti:Sapphire or dye as the laser gain medium, Matisse 2 provides an unprecedented tuning of >470 nm and linewidths down to 30 kHz, with fully integrated PDH lock to X reference cell.

Matisse 2 TR and DR

The Matisse 2 R-Series ring laser with its mechanically quiet design provides excellent passive stability and ultra-low noise, single-frequency operation. Electronically controlled wavelength-selecting elements—a birefringent filter, a thick etalon, and a thin etalon—keep the laser centered on a single longitudinal mode. This enables long, mode-hop-free wavelength scans while maintaining constant, low-noise output power levels.

The Matisse 2 TR Ti:Sapphire ring laser provides a spectral linewidth of <4 MHz and can be readily upgraded to the higher resolution Matisse 2 TS. In fact, because of its modularity, any Matisse 2 laser can be field upgraded to either a Ti:Sapphire or dye gain medium, or to a configuration with higher resolution – from an R-Series to an S-Series or an X-Series.

Matisse 2 TS and DS

The Matisse 2 S-Series actively-stabilized ring laser incorporates an external reference cavity with feedback to a cavity-length-stabilizing fast piezo-driven mirror. To guarantee a truly independent frequency feedback signal, the reference cavity is thoroughly isolated against thermal and mechanical perturbations and is fiber coupled outside the laser housing.

The Matisse 2 TS actively-stabilized Ti:Sapphire ring laser has an internal spectral linewidth of <50 kHz, while the Matisse 2 DS dye ring laser provides a spectral linewidth of <200 kHz.

Matisse 2 TX and DX

The Matisse 2 X-Series ring laser provides spectral linewidths to <30 kHz for the Ti:Sapphire active gain medium, and <100 kHz for the dye laser. This ultra-narrow linewidth is the result of very fast cavity length stabilization with a response bandwidth in the MHz range. This is achieved by use of an intra-cavity electro-optic modulator (EOM).

Also key to achieving this ultra-narrow linewidth is the feedback error signal from the external reference cavity using the Pound-Drever-Hall stabilization scheme and a high finesse external reference cavity. Pound-Drever-Hall provides an unambiguous measure of wavelength position uninfluenced by laser intensity fluctuations.

Matisse 2 TX-light

The Matisse 2 TX-light fills the linewidth gap between the Matisse 2 TS and the Matisse 2 TX. It utilizes the Pound-Drever-Hall locking technique and the high-resolution reference cavity of the TX to provide the feedback signal to the fast Piezo-driven mirror of the TS. The negligible sensitivity of the Pound-Drever-Hall method to intensity fluctuations, as well as the extremely stable locking it provides, lead to laser linewidths of less than 50 kHz.
