45mm Large Aperture Faraday Isolator | High Power TGG Crystal Free-Space Optical Isolator for 1064nm Laser Systems

Crystro's Large Aperture Faraday Isolator (Model: FCR-2026-08-22-01) is engineered for high-power laser systems requiring large beam cross-sections and robust backward-reflection suppression. Built around our in-house grown TGG from 20 mm to 45 mm, making it ideal for kilowatt-class fiber lasers, laser welding and cutting machines, and large-scale laser amplifier chains.

Unlike magneto-optical glass alternatives, our single-crystal TGG offers superior Verdet constant uniformity (< 1 % across the full aperture), lower absorption coefficient, and higher laser damage threshold. The precision-machined permanent magnet assembly provides a homogeneous axial magnetic field, ensuring consistent 45° Faraday rotation across the entire clear aperture and maintaining isolation stability even at elevated operating temperatures.

Key Features:

Single-crystal TGG:In-house grown, Verdet uniformity < 1 %, absorption < 0.003 cm⁻¹ @ 1064 nm

High isolation :Typical > 33 dB @ 25 °C, > 28 dB at rated power

Low insertion loss:< 0.35 dB

Customizable wavelengths:Standard 1064 nm; 532/808/1030/1080 nm on request

Applications:

Industrial laser processing production lines
High-energy laser research facilities
High-power fiber laser output protection (kW class)
Laser welding and cutting machine integration

why Choose Crystro Large Aperture Isolators

From TGG crystal growth to final device assembly, Crystro controls every production step, ensuring consistent quality and shorter lead times.
Wavelength, aperture, power rating, cooling method, and housing dimensions can all be tailored to your specific laser system requirements.
