LiNbO3 is also one of the most attractive materials for optoelectronics. A great variety of devices has been developed based upon this material having unique electro-optical, photoelastic, piezo-electric and non-linear properties combined with good mechanical and chemical stability and wide transparency range.
Altechna offers a lot of products made of high quality LiNbO3 crystals of both Acoustical and Optical grades. Typically, Czochralsky grown along Z-axis boules are used with sizes up to 80 mm in dia. and 100 mm in length. Other boules orientations can be applied for some purposes (SAW surstrates, piezotransducers).
Features:
| High homogeneity | |
| Wide transparency range | |
| Unique electro-optical, photoeleastic, piezoelectric and nonlinear properties | |
| Good mechanical and chemical stability | |
| Absorption loss < 0,1 %/cm @ 1064 nm |
Innovation point: Through the growth equipment modification,we create simulation of crystal growth system and can design crystal shape. The computer chip control the changing of crystal shape according to crystal growth status, through the processing of precision sensor signals. We self-design a set of graded composite temperature structure. With the help of it, the temperature gradient in crystals, melt and the solid liquid interface reach the good state for optical crystal growth.
