CW single-frequency ring Dye laser, model "DYE-SF-077"
The DYE-SF-077 laser cavity has horizontal orientation, the optical mounts
of the cavity elements are attached to a rigid base plate, which is further
stabilised by a volumetric framework with three invar rods underneath.
Additional passive stability of the position of cavity elements is provided
by the vibration isolating design of the laser base.
