TGG & Faraday Rotator
Features:• Extremely High Verdet Constant (~ -40 rad T-1m-1)
• Low optical losses (<0.1%/cm)
• High thermal conductivity (7.4W m-1K-1)
• High laser damage threshold (>1GW/cm2)
• Main Application: Faraday Rotator, Optical Isolator etc.
TGG (Terbium Gallium Garnet) single crystal is currently the best and widely used magneto-optical material in Faraday rotator and isolator due to its extremely high Verdet constants ( -40 rad T1 m1) in the range of 400nm-1100nm(excluding 475-500nm). By placing a rod of this material in a strong magnetic field, Faraday rotation angles of over 45° can be achieved. This allows the construction of Faraday rotators which are the principal component of Faraday isolators, devices which transmit light in only one direction.
Faraday Rotator Glass
Magneto Optical Glass / Faraday rotator glass materials Tb-10, Tb-12 and Tb-15 are designed for laser light flux output control in the magnetic field in visible and near-IR spectral range. It is used in manufacture of faraday rotating components based on Faraday rotation of the light polarization plane, such as optical isolators, circulators, magneto-optical modulators, fast optical switches, interleavers, laser gyroscopes, goniometric devices, magneto-optic storage and optical information process system, current measuring transducers for magnetic field measuring and high-voltage transmission line, new generation current sensors, wave guides, astrology, spaceflight control, satellite survey and other functional devices. TG-28 is characterized by a high verdet constant and a lower nonlinear refractive index to avoid selffocusing in high power laser system.
