LiTaO3 crystal is also widely used E-O crystal, due to its optical, NLO and E-O poperties similar to those of LiNbO3 crystal, but with higher damage threshold (> 500 MW/cm2 for ns pulsed). Main properties include:
  • Transparent Range: 0.4 - 5.0 μm; E-O Coefficient: r33=30.4; 
  • Refractive Indices: no=2.176, ne=2.180 @ 633 nm.
Maximum LiTaO3 SAW wafer size we can offer is 6 inch in diameter.

Red Optronics provide LiTaO3 in as-cut boules, wafers or slices. Our production capabilities include:

Boules: 
  • Diameter: f40mm ~ 102mm 
  • Length: 50mm ~ 150mm 
  • Orientation: X, Z, 36°Y, 42°Y, 128°Y 
  • Polish: 0.016mm 
Wafers: 
  • Diameter: f40mm ~ 102mm 
  • Length: 0.2~1.2mm 
  • Orientation: X, Z, 36°Y, 42°Y, 128°Ys 
  • Flatness: 
    <10mm for f40 ~ 65mm

Innovation point: Through the crystal growth machine's modification in rotating and lifting system, the stability of crystal growth interface and growth rate become higher. Also the defects caused by the influence of crystal rotating and rising disturbance on the solid-liquid interface during the crystal growth process are reduced. 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. The ultra low gradient interface growth temperature field we self-designed make the quality of optical crystals much better.
