Customized Lithium Niobate Piezoelectric Ring Wafer Orientation Z-cut or 36Y-cut
Lithium Niobate (LiNbO3, LN) crystal is a negative uniaxial crystal and is one of the most comprehensively characterized optical materials. LN crystal has a wide range of transparency in visible and mid-infrared light and good chemical and mechanical stability, which can be used as an infrared birefringent material.
LN (lithium niobate) crystal has many advantages such as high electro-optic coefficient, wide optical transparency window and high optical quality crystal. LN (lithium niobate) crystal is the preferred material for optical modulation and Q-switch in near-infrared and infrared bands. For the electro-optic modulator, the crystal performs zero residual birefringence along the direction of light propagation with Z-cut, or non-zero residual birefringence and max effective electro-optic coefficient with X-cut. For Q-switches, the crystal is typically Z-cut, with zero residual birefringence and a transverse electric field applied in the direction of light propagation. The piezoelectric ring in LN has a defect at high repetition rates, but this defect can be overcome to some extent by appropriate piezoelectric damping design.

FAQs:
A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.
A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
A: Yes, we would suggest you go with the courier agent you are most familiar with (DHL, FedEX, UPS etc.). We can ship via your account. And, of course, we will pack the products safely in acceptable size to help you save the shipping cost. If you need us to take care of the freight, it’s also not a problem. We also have good discount with the international courier companies.
