The Spectra-Physics^® Matisse^® series is a family of state-of-the-art single frequency ultra-stable, narrow linewidth tunable ring lasers. Long-term wavelength stability and low output noise is assured with the Matisse laser's INVAR baseplate and acoustically-engineered housing. Each laser is tuned using a precise long-travel piezo to allow single-frequency scanning over 50 GHz while maintaining stable power output without mode hopping. Controlled with high-performance digital signal processing (DSP) technology, Matisse lasers feature user-friendly, open-source software. Together these features provide unprecedented spectral resolution and stability.

With its modular design, the Matisse lasers can be configured for either Ti:Sapphire or a dye solution as the laser gain medium, and for linewidths ranging from 20 MHz down to 30 kHz.

The dye ring laser versions of the Matisse laser are equipped with an innovative high-pressure circulator and sapphire dye jet. The circulators prevent the formation of circulating bubbles and inhibit the transmission of shock waves and vibrations into the liquid jet. This results in a “silent” gain medium that produces the narrowest possible output linewidth with minimum amplitude noise.
