Abstract :
The frequency excursion due to intermittent laser beam irradiation on the surface of a SAW device plate is analyzed by assuming that only one dimensional thermal stress in the propagation direction of SAW on the surface of the plate exists and a diameter of the beam is infinitesimal. As a result, specimen plates immune to transient environmental temperature change are made and their frequency trends better than those of the ST-cut plate are shown
