Semiconductor LN Crystals by CZ Czochralski method For Optical application
Description
Lithium niobate crystals have excellent electro-optic,
acoustooptic, piezoelectric and nonlinear properties. Lithium
niobate crystal is an important multifunctional crystal with good
nonlinear optical properties and large nonlinear optical
coefficient. Moreover, non-critical phase matching can be realized.
As an electro-optical crystal, it has been used as an important
optical waveguide material. As a piezoelectric crystal, it can be
used in the production of low frequency SAW filters, high power
high temperature resistant ultrasonic transducers and so on. Doped
lithium niobate materials are also widely used. Mg:LN can greatly
improve the anti-laser damage threshold, and promote the
application of lithium niobate crystals in the field of nonlinear
optics. Nd:Mg:LN crystal, can achieve self-doubling effect; Fe:LN
crystals can be used for holographic storage in optical volumes.
Application
Lithium niobate crystal is one of the most widely used new inorganic materials, it is a good piezoelectric energy exchange material, ferroelectric material, electro-optical material, lithium niobate as electro-optical material in optical communication to play the role of light modulation. Its single crystals are important materials for optical waveguides, mobile phones, piezoelectric sensors, optical modulators and a variety of other linear and nonlinear optical applications.
Production method
Lithium niobate was prepared using lithium carbonate and niobium
pentoxide as raw materials by pulling method: lithium carbonate and
niobium pentoxide were put into a platinum crucible and crystals
were grown along the direction (001). In order to obtain high
quality colorless transparent cylinder, it is necessary to add an
appropriate size of electric field when the temperature of the two
end faces in the two directions of crystal growth is slightly
higher than the Curie temperature, and then form the crystal to
cool the crystal to room temperature, that is, to prepare lithium
niobate crystal.
