Abstract
The crystal is solid CdTe or GaAs for modulating a laser beam. The mount comprises Al2 O3 or BeO ceramic between the crystal and a U-shaped aluminum housing on three sides to provide low stray capacitance and high thermal conductivity to the cooled housing. A layer of lead between the ceramic and the housing enhances the acoustic damping of the structure. Electrodes are attached to the crystal, with lead used to enhance dissipation of acoustic energy. in contacting flexible tabs on the electrodes with terminals no pressure or stress is transmitted to the crystal, thereby eliminating a problem of stress-induced birefringence.
