Piezoelectric Lithium Niobate Wafer For SAW Interdigital Transducer Making

Piezoelectric Lithium Niobate Wafer For SAW Interdigital Transducer Making

Lithium niobate is transparent between 0.25 and 5.3 μm. It can be used in visible, near IR and middle IR region. As any ferroelectric, lithium niobate demonstrates piezoelectric effect, nonlinear optic effects, photoelastic effect and Pockels effect (linear electro-optic effect). What makes lithium niobate stand out is that the coefficients characterizing these effects are several times greater than those of similar ferroelectrics, facilitating its usage for various applications.

Due to its high electro-optical coefficients, lithium niobate is used for optical amplitude and phase modulators, Pockels cells, laser Q-switching modulators. Non-linear optical properties of lithium niobate allow its application for optical parametric oscillators and parametric amplifiers for a wide wavelength range. Lithium niobate is the best choice for second harmonic generator in Nd:YAG laser operating at 1.064 μm, as well as semiconductor lasers operating at 1.3 and 1.55 μm. It should be noted that non-doped lithium niobate exhibits high photorefraction. Therefore in high-power laser applications, magnesium oxide-doped crystals (MgO:LiNbO3) are used. They have a higher Laser Damage Threshold. At the same time, the doping has no effect on the optical properties of the crystal.

FAQs:

1. Q: What are the products you mainly work on?

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.

2. Q: Can you accept product customization?

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.

3. Q: Can you deliver the goods via our courier agent?

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.

4. Q: How can you guarantee we get what we want safely?

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.
