NEW! PAVOS+ Ultra 4 mm Faraday Isolators - 1010 nm to 1080 nm

 

The PAVOS+ Ultra line of Faraday devices offers roughly 1/10th the absorption and thermal lens focal shifta and can theoretically provide ten times lower non-linear refractive index compared to the standard PAVOS+ isolators. This results in less Kerr Lens focal shift and a lower B-integral protecting against catastrophic whole beam self-focusing. The PAVOS+ Ultra line has been specifically designed to meet the needs of the high power and high energy 1 µm (1010 nm to 1080 nm) laser market with stable performance up through 150 W of average power compared to 80 W for the standard PAVOS+. 

For laser systems having large distances between amplification stages, the reduced thermal lens focal shift of the PAVOS+ Ultra results in greater coupling efficiency and simpler optical design. 

Our PAVOS+ Ultra rotators deliver industry-best laser reliability and performance. The PAVOS+ Ultra family of Faraday devices provide superior isolation, especially at higher average power levels, while maintaining very high transmission values. 

EOT's PAVOS+ Ultra 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.
