Abstract
A floating mirror plate for a laser is suspended in a resonant cavity structure by graphite fiber rods. The cavity structure positions the mirror mounting plates and maintains a highly stable longitudinal spacing of the mirror mounting plates, despite thermal expansion and contraction of other parts of the cavity structure during operation of the laser. The graphite rods are associated with metal tubes and metal bracket support plates for resisting torsion by a construction which does not clamp the metal tubes onto the graphite rods. This construction permits relative movement, in a longitudinal direction, between the metal tubes and the graphite rods to accommodate thermal expansion and contraction of the metal tubes occurring during operation of the laser. The floating plate structure also embodies a rod arrangement in which the rods are not required to be aligned with contact pads for mirror adjusting screws.
