Magneto-optical crystals

Magneto-optical crystals

Magneto-optical crystals are crystalline materials with magneto-optical effect. Magneto-optical crystals can be separated right into three groups:

  • Ferromagnetic magneto-optical crystals
  • Paramagnetic magneto-optical crystals
  • Diamagnetic magneto-optical crystals

The Magneto-optical crystals are extensively used in optical interaction, computer storage space, microwave gadgets and various other fields as a result of their large Faraday impact, reduced wavelength absorption coefficient, high permeability and also high magnetization. Magneto-optical crystals can be widely made use of in optical device production fields such as optical modulator, optical isolator, optical ring, optical phase shifter, optical button, in addition to optical storage space, optical display, optical recorder, microwave tools, laser gyro and also various other storage as well as microwave gadget manufacturing areas.

TGG crystals

Faraday isolators and spinners based upon Terbium gallium garnet (TGG) have actually continued to be the market requirement previously, as TGG has actually been made use of in the isolators as well as rewriters sector as Faraday crystals with modern-day crystal development approaches and also specific control of resources.

TGG crystal is the very best magneto-optical material for making Faraday optometer as well as isolator, suitable for wavelength 400-1100nm (omitting 470nm-500nm). TGG solitary crystal has high magneto-optical constant, low light loss, high thermal conductivity and high laser light damages limit, and is commonly used in YAG, Ti-doped sapphire and various other multistage amplification, ring type, seed injection laser.

The main advantages

  • Large magneto-optical continuous (35 Rad T-1 m-1)
  • Reduced light loss (<0.1%/ centimeters)
  • High thermal conductivity (7.4 W m-1K-1)
  • High laser damages threshold (>1GW/cm2)
  • Big Verdet Continuous (35 Rad T-1 m-1)
  • Low optical losses (<0.1%/ cm)
  • High thermal conductivity (7.4 W m-1K-1)
  • High laser damage limit (>1GW/cm2)

TSAG crystals

TSAG is the key isolation material of the next generation fiber laser. As an excellent noticeable and also infrared magneto-optical crystal, TSAG has the advantages of high Verdet constant, exceptional thermal and mechanical residential or commercial properties.

Terbium-scandium-aluminum garnet (TSAG) crystals are ideal magneto-optical products for both noticeable and infrared wavelengths (wavelength array: 400-1600nm). TSAG crystal has the advantages of high stability, good thermal and also mechanical buildings, and is a vital crystal for the next generation of high power laser.

Compared to TGG crystals, TSAG has greater field continuous as well as reduced absorption loss, which can make the isolator smaller sized, and also is an optimal product for optical isolators with high power.

The main advantages

  • Verdet constant 20% more than TGG (65radT-1m-1 at 1064nm)
  • Low Absorption(<3000ppm/cm at 1064nm)
  • High power certified
  • Reduced thermally-induced birefringence
  • Make isolator extra compactand smaller

CeF3 crystals

Rare earth trifluoride crystals, such as CeF3 and also PrF3, are outstanding new magneto-optical materials without “core” and have high utilization price of crystal spaces.

The Verdet consistent worth of CeF3 crystal is the same as that of TGG crystal at 1310nm wave size, which indicates that the crystal can be ideal for Faraday isolator in close to infrared band, and also turns into one of the potential candidates to change business magneto-optical products.

Faraday revolving glass

Faraday magneto-optical glass (RAre-earth Faraday magneto-optical glass) is a new type of useful material, which has a wide application possibility in the field of optical fiber communication and also sensing as a result of its great anisotropic harmony, excellent magneto-optical homes as well as inexpensive.

Magnetically revolving glass, likewise referred to as Faraday rotating glass, is a brand-new transparent optical functional material established in recent years. It can turn the polarization aircraft of a beam of light of linearly polarized light parallel to the electromagnetic field. Magnetic optically rotating glass is the core product of modern extensive items, which is extensively used in the high-tech areas of optics, electricity and magnetism. For instance, this material can be made use of to make optical isolator, magneto-optical modulator, magneto optical attenuator, magneto optical switch, magneto optical sensor and also a selection of high-precision gyroscope in fiber communication.
