AI Overview

Yttrium Orthovanadate (

cap Y cap V cap O sub 4

) is a positive uniaxial birefringent crystal grown using the Czochralski method, widely produced in China for photonics applications. It is prized for its large birefringence (

at 630 nm), wide transparency range (

), and high physical/chemical stability. It acts as a superior substitute for calcite and rutile, commonly utilized in beam displacers (BD), optical isolators, and circulators.

High Birefringence: With a large
$delta n$
, it enables short optical path lengths, ideal for compact devices.
Excellent Transparency: Covers 400 nm to 5000 nm, suitable for visible and infrared, particularly fiber optic wavelengths (
).
Mechanical Strength: Higher hardness (Mohs 4-5) compared to calcite, allowing better fabrication, polishing, and longevity.
Uniaxial Structure: Zircon tetragonal structure (
), ensuring high-quality crystal growth (Czochralski method).
