MgO dope optical wafer

Product Description

4 inch Diameter LiNbO3 Wafer 0.25mol% Er dope or 5mol% MgO dope for Optical Applications
 

LiNbO3 (LN) crystal has stable physical, chemical and mechanical properties, high temperature resistance, corrosion resistance, easy processing; It has a high Curie temperature (To), no phase transition from room temperature To Curie temperature, and is not easy To depolarize, can be used repeatedly; In addition, when different kinds of ions are mixed into LiNbO3 crystal, the crystal will show a variety of special properties, which can be used as optical waveguide amplifier, frequency doubling converter, optical storage medium, etc. Therefore, the research on the properties of lithium niobate crystal and doped lithium niobate crystal has been the focus of research at home and abroad.

 

BonTek is capable of providing doped LN wafers: Er:LN, MgO:LN and Fe:LN with customized doping dose. We can also provide black reduced LN wafers in 3 inch, 4 inch, 6 inch for all cut angles! For 128°Y and Z-cut up to 8 inch diameter.

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.
 

  1. 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.
 

  1. 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.
 

  1. 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.
 

  1. Q: Can we visit your factory?

A: Sure. Factory inspection is important for large quantity purchase and long-term cooperation. Face to face discussion is what we mostly confident with. During the past years, big names around the world have witnessed our progress in factory build-up. These days, due to the Covid-19 pandemic, we also had the experience of videoconferencing with global buyers.
