Matisse 2 DR

Passively Stabilized Dye Ring Laser

In the Matisse DR dye ring laser, frequency selection is done by a birefringent filter, a thin etalon and a thick etalon. The unique mechanics of the long travel piezo mechanics allows single frequency scanning over 60 GHz without mode hopping. The Matisse DR can be upgraded into the higher resolution Matisse DS (cavity length locked to reference cavity by piezo controlled mirror) or DX versions (additional intra-cavity EOM), or converted into the Matisse TR Titanium:Sapphire ring dye laser.
