Laser Crystal TeO2

Item No.: TO2
Our ability:can provide customers with Ф 2 inch, 3 inch, 4 inch Ф Ф crystal rods and various types.
Tellurium dioxide (TeO2) is a solid oxide of tellurium. It is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO2, and the synthetic, colourless tetragonal (paratellurite), α-TeO2. Most of the information regarding reaction chemistry has been obtained in studies involving paratellurite, α-TeO2.

Running ability:
We can provide customers with Dia:2 inch, 3 inch, 4 inch wafers and crystal rods. 
And other customized square ships etc.

  
Application:
Can be made into all kinds of acousto-optic device, such as acousto- optical deflector, acousto-optic q-switched, surface acoustic wave devices, etc, thus putting these crystals are widely used in laser radar, television, and a large screen display device scanning optical memory, photon computer and laser communication, etc.
TeO2 crystal is a kind of acousto-optic material with high quality factor.There are good birefringence and optical rotatory properties, and the velocity of propagation is slow along [110].If under the same clear aperture, use TeO2 single crystal made the resolution of the acousto-optic device can increases the order of magnitude, the response speed, driving power is small, high diffraction efficiency, stable and reliable performance, etc
