Product Description
Z-Cut X-Cut LiNbO3 Crystals Wafer Optical Grade Both Sides Polish
The sound velocity for the longitudinal waves in LiNbO3 propagating along the principal axes is for the Z-direction, 7.271*10^5 cm/s; for the Y-direction, 6.549*10^5 cm/s; and for the X-direction, 6.580*10^5 cm/s.32,43,44 Applying these values to the case of a 10*10*0.5 mm3 Y-cut LNO crystal, the thickness extensional mode should appear at 6.58 MHz. The closest observed peak is centered at a slightly lower frequency of 6.34 MHz, which may be explained as a consequence of the clamping effect of the Metglas foils. The calculated length extensional resonances along the X and Z directions (327.5 kHz and 363.5 kHz, respectively) can be attributed to the peaks observed at 314 kHz and 355 kHz.
