Functional Single Crystals

Fujikura Limited produces functional single crystals for usages in process and medicine, as well as for utilization in various types of electronic equipment, the light power of laser source has increased at higher levels year by year. Optical isolators are used to prevent the element from being destroyed by the laser light when it returns to the output device. The high resistance for laser damage is also required in the optical isolators because of the recent demand in the light power of laser source. Fujikura has developed the single crystals that can be employed in the optical isolators of high power laser light source.

 The company has also developed the highly functional single crystals, such as the nonlinear optical crystals for laser light and the wafers for light emitting device, by using their cultivated technology for the material design and the crystal growth.
