Flatness λ/10 Magnetic Sensor TGG Crystal


Applications:

  • Faraday Rotator;

  • Magnetic sensor

  • Optical Isolator

Description:


Terbium gallium garnet is an attractive Faraday-rotating crystal suitable for constructing magneto-optical isolators, magneto-optical switches, magneto-optical modulators and so on,widely used in YAG, Ti-doped sapphire and other multi-stage amplification, ring type, seed injection laser

is a crucial category of magneto-optical materials for use in the visible and the near-infrared spectral regions((400-470nm and 500-1500nm)).

The TGG crystal possesses a large Verdet constant (35 RadT−1m−1 at 1064 nm), high thermal conductivity (7.4 Wm−1K−1), low optical losses (< 0.1%/cm) and high laser damage threshold (> 1 GW/cm2).
