The Spectra-Physics® Matisse® series is a family of state-of-the-art single frequency ultra-stable, narrow linewidth tunable ring lasers. The Matisse system has the industrys highest output power, the narrowest external linewidth, the broadest tuning range, and the most flexible architecture.Coupled with the Millennia® eV pump laser, the Matisse produces over 6.5 W of output power. With flexibility to be configured for either Ti:Sapphire or dye as the laser gain medium, Matisse provides an unprecedented tuning of >465 nm and linewidths ranging from 20 MHz down to 30 kHz.Long-term wavelength stability and low output noise is assured with the Matisse laser's steel 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.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.
