PAVOS 2mm Small Aperture Faraday Rotators
Description
EOT's PAVOS line of Faraday devices builds on over 30 years of experience in succesfully protecting lasers from destabilizing and potentially damaging back reflections. The PAVOS line has been specifically designed to meet the needs of high power and high energy 1 µm (1010 nm to 1080 nm) lasers. Our PAVOS rotators and isolators deliver industry-best laser reliability and performance while providing superior isolation and maintaining very high transmission. EOT's PAVOS products rely on the Faraday effect from high Verdet constant, low absorption materials to rotate the plane of linearly polarized light in the forward direction and an additional 45° of non-reciprocal rotation in the reverse direction. The PAVOS is available as a rotator or an isolator.

Frequently Asked Questions
The PAVOS line of Faraday devices is used in ultrafast, pulsed, and CW lasers, microelectronics, medical systems and device manufacturing, micromachining, and particle acceleration.
The PAVOS line of Faraday devices is completely passive, rugged, and suitable for harsh operating environments. It has specified performance to 50 W and has been tested to >400 W. It also has optically contacted PBS cubes for improved damage threshold and input polarization adjustability.
The specifications of the PAVOS line of Faraday devices include small aperture rotators and isolators with a clear aperture of 2 mm or 5 mm, and large aperture rotators and isolators with a clear aperture of 8 mm, 12 mm, 15 mm, 20 mm, 25 mm, 35 mm, or 45 mm. The peak transmission is >98% for small aperture rotators, >95% for small aperture isolators, >98% for large aperture rotators, and >92% for large aperture isolators. The peak isolation is >33 dB for small aperture isolators and >30 dB for large aperture rotators, with typical isolation of >37 dB for small aperture isolators and >35 dB for large aperture isolators.
The PAVOS rotator and isolator both rely on the Faraday effect from high Verdet constant, low absorption materials to rotate the plane of linearly polarized light in the forward direction and an additional 45° of non-reciprocal rotation in the reverse direction. The difference is that the isolator provides superior isolation while maintaining very high transmission, while the rotator does not provide isolation.
The PAVOS line of Faraday devices is used to protect high power and high energy 1 µm (1010 nm to 1080 nm) lasers from destabilizing and potentially damaging back reflections.
