Matisse 2 DS

Actively Stabilized Dye Ring Laser

The Matisse DS is based on the Matisse DR dye ring laser. Additional cavity length stabilization by an external reference cavity and a fast piezo driven mirror narrows the linewidth down to 250 kHz. The unique long travel piezo mechanics allows single frequency scanning over 60 GHz without mode hopping. The Matisse DS can be up-graded into the higher resolution DX version, or converted into the Matisse TS ring Titanium:Sapphire laser.
