TSAG Crystals For Faraday Isolator Low Absorption Than TGG Crystals

 

Description:

 

TSAG Faraday crystal is an ideal magneto-optical crystal, which is mainly used in the wavelength range of 400-1600 nanometers, namely the visible and infrared bands. TSAG is an indispensable crystal for the next generation of high-power lasers due to its advantages of high constant, good thermal and mechanical properties. Compared with TGG, the Verdet constant at 1064 nm of TSAG is 20 % higher and the absorption is 30 % lower. Recently, the optical and scintillation properties of TSAG (Tb3Sc2Al3O12) crystal was investigated, and capabilities to be used as a scintillator screen was demonstrated.

 

 

Features:

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

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

  • High power compliant;

  • Low thermally-induced birefringence;

  • Making the isolator small.

 

Applications:

  •  

    Faraday isolator based on TSAG crystal for high power lasers

  • In this study a Faraday isolator based on a new magneto-active medium - TSAG crystal - providing an isolation ratio of more than 30 dB at laser power up to 500 W has been constructed for the first time. Measurements and estimations demonstrate that with the expected reduction in the absorption coefficient of grown crystals and the use of optimal orientation of crystallographic axes it would be possible to construct a traditional FI for a laser power of more than 1 kilowatt.

  • Imaging applications:Scintillation properties of TSAG crystal for imaging applications

    Optical and scintillation properties of TSAG (Tb3Sc2Al3O12) crystal was investigated, and capabilities to be used as a scintillator screen was demonstrated. In photoluminescence (PL) spectra, some emission lines due to Tb3+ 4f-4f transitions appeared from 500 to 700 nm. PL quantum yields of TGG and TSAG were 6.5 and 50.9%, respectively. When irradiated by X-rays, these crystals showed intense scintillation, and the emission wavelengths were the same as those in PL spectra. The scintillation decay times of TSAG was 678 μs, respectively.
