Features:
The large Verdet constant (48radt-1m-1 at 1064nm) is about 20% higher than that of TGG;
●Low absorption (< 3000ppm / cm at 1064nm);
●High power compatibility;
●Low thermal birefringence;
Applications:
●Faraday rotator
●Isolator
Terbium scandium aluminum garnet (TSAG) crystal is an ideal magneto-optical material, suitable for visible and infrared wavelengths (wavelength range: 400-1600nm). TSAG crystal has the advantages of high stability, good thermal and mechanical properties, which is essential for the next generation of high-power lasers.
Compared with TGG crystal, TSAG has higher feld constant and lower absorption loss, which makes the isolator more compact and is an ideal material for high power optical isolator.
