Lateral field excitation and coupled modes in AT quartz: synchrotron radiation X-ray topography

Using the synchrotron radiation delivered by a DCI storage ring, plano convex AT resonators excited by a lateral field are studied by the X-ray topography technique. Different overtones and anharmonics of the three types of the thickness modes are observed. Coupled modes in fundamental AT plane resonators are shown and the reasons for their appearance are analyzed. >
