Ra 1nm Lithium Niobate Wafer used in Visible, Near-Infrared and Mid-Infrared Regions
Lithium niobate is transparent between 0.25 and 5.3 μm. It can be used in visible, near-infrared and mid-infrared regions. Like any ferroelectric, lithium niobate has piezoelectric effects, nonlinear optical effects, photoelastic effects and Pockels effects (linear electro-optic effects). What makes lithium niobate stand out is that the coefficients characterizing these effects are several times larger than those of similar ferroelectrics, which favors its application in a variety of applications.
Because of its high electro-optic coefficient, lithium niobate is used in optical amplitude and phase modulators, Pockels batteries, and laser Q-switch modulators. The nonlinear optical properties of lithium niobate make it suitable for optical parametric oscillators and parametric amplifiers with wide wavelength range. Lithium niobate is the best choice for the second harmonic generator in 1.064 μm Nd:YAG laser and 1.3, 1.55 μm semiconductor laser. It is noteworthy that undoped lithium niobate has a very high refractive index of light. Therefore, magnesium oxide doped crystals (MgO:LiNbO3) are used in high power laser applications. They have a higher laser damage threshold. At the same time, the doping has no effect on the optical properties of crystal.

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.
A: The wafer products are fragile and sometimes expensive. The last thing, as the manufacturer, we want to see is the products we make were damaged during courier. As a result, we will pack the wafers adequately and put them in a proper carton filled with buffer sponge. However, accidents are inevitable sometimes. So, please follow the “Acceptance check” steps shown in the drawings below. If the unwanted happened, we will either give the replenishment or refund if you follow the checking steps.
