8mm Terbium Gallium Garnet TGG Crystal Block Double Sided Polishing

Terbium Gallium Garnet (TGG) Crystal Block 8*8*8mm Double-Sided Polishing

Introduction :

Terbium gallium garnet (Tb3Ga5O12, TGG) crystal has a large Verdet constant, low transmission loss, high thermal conductivity, and a high laser damage threshold. It is the best choice for making Faraday isolators in high-power all-solid-state lasers.

Main Features :

• Large Size Boule Diameter: up to 4”
• Extinction Ratio Typical: >35 dB High Grade: >40 dB
• Verdet Constant 40 rad/T/m at 1064 nm
• Refractive Index 1.95 at 1064 nm

Main Advantages :

1. Large Verdet Constant:35 Rad T-1m-1

2. Low Optical Losses : <0.1%/cm

3. High thermal conductivity: 7.4W m-1K-1

4. High laser damage threshold :>1GW/cm2
