  TSAG

  
  


• TSAG is a key isolator material for next generation fiber laser. As an ideal magneto-optic crystal in visible and infrared regions,TSAG has the advantages of high Verdet constant,excellent thermal and mechanical properties.

Main Features of TSAG:

     •   Large Verdet constant(48radT-1m-1 at 1064nm),about 20% higher than that of TGG;

     •   Low absorption(<3000ppm/cm at 1064nm),about 30% less than that of TGG;

     •   High power compliant;

     •   Low thermally-induced birefringence;

     •   Making the isolator small.

 

Main Applications:

     •   Faraday Rotator;

     •   Optical Isolator.
