MgO doped Lithium Niobate wafer

The LiNbO3 (LN) crystal possesses stable physical, chemical, and mechanical properties, exhibiting high-temperature resistance, corrosion resistance, and ease of processing. It has a relatively high Curie temperature (Tο) with no phase transition from room temperature to Curie temperature, and it is resistant to depolarization, allowing for repeated use.

Moreover, when different types of ions are mixed into the LiNbO3 crystal, it exhibits various special properties, making it suitable for applications such as optical waveguide amplifiers, frequency-doubling converters, and optical storage media.

For example, 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.

CQT 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!
