Product Description

TGG Single Crystal with AR Coating for 1064nm Applications

Terbium gallium garnet (Tb3Ga5O12) is a premium magneto-optical crystal engineered for high-performance laser systems operating in the 400-470nm and 500-1500nm spectral ranges.

Key Performance Features

Large Verdet Constant: 35 Rad T⁻¹m⁻¹ at 1064nm
Low optical losses: <0.1%/cm
High thermal conductivity: 7.4W m⁻¹K⁻¹
Exceptional laser damage threshold: >1GW/cm²
Twice the Verdet constant compared to terbium-doped glass
Thermal conductivity order of magnitude greater than typical glass
Lower optical losses than Tb-doped glasses

Primary Applications

Faraday Rotators for laser isolation
Optical Isolators in high-power laser systems
Magneto-optical switches and modulators
YAG, Ti-doped sapphire, and multi-stage amplification systems
Ring type and seed injection laser configurations
