Thermal Compensation in GaPO4 Beam Resonators: Experimental Evidence for Length Extensional Mode

Fabrice Sthal, Emmanuel Bigler, and Roger Bourquin

ABSTRACT Temperature effects in gallium orthophosphate (GaPO4) vibrating beams are reported. In addition to the well-known, thickness-shear AT-cut, temperature-compensated cuts exist in GaPO4 for length extensional modes. Experimental evidence of a temperature-compensated cut in GaPO4 rectangular beam resonator vibrating in length extension is given.
