Product Description

Product Description

                                      

Lithium niobate (LiNbO3) is a ferroelectric material suitable for a variety of applications. Its versatility is made possible by the excellent electro-optic, nonlinear, and piezoelectric properties of the intrinsic material. It is one of the most thoroughly characterized electro-optic materials, and crystal growing techniques consistently produce large crystals of high perfection.

Application

  • Frequency doubling for wavelengths >1μm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices;

  • Pockel cells, Q-switches, and phase modulators;

  • Waveguide substrates, surface acoustic wave (SAW) wafers.

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.
