Faraday Rotator Glass

Nd doped glasses	Erbium laser glasses	Ytterbium doped glasses	Faraday rotator glasses

Faraday rotator glass has been used for magneto-optical isolator, switch, modulator and sensor. It is a high verdet constant glass in common uses, characterized by a high verdet constant and a lower nonlinear refractive index n2 to avoid self-focusing in high power laser system. We provide two typew of faraday rotator glasses:

TG20 Faraday rotator glass: is a high Verdet constant glass in common uses.

TGP20 Faraday rotator glass: is characterized by a high verdet constant and a lower nonlinear refractive index n2 to avoid self-focusing in high power laser system.
