Thermal Frequency Behavior in Contoured Quartz Crystal Plates Induced by Direct Irradiation of Laser Beam,
Abstract
The oscillation frequency behavior of the quartz crystal plates is observed, while a laser beam as a kind of probe is irradiating different points of their principal surfaces. Such frequency behavior is characteristic to the respective angle of cut and is independent of the geometry and type of the electrode or support. There are three kinds of region on an AT-cut plate which show different types of thermal frequency behavior. The amounts of the frequency shifts in IT-cut and SC-cut plates are about 1/5 to 1/10 times those in AT-cut plate for the same irradiation power of the laser.
