Our PAVOS Ultra Faraday rotators and isolators deliver industry-best laser reliability and performance while providing superior isolation and maintaining very high transmission. Our 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. The PAVOS is available as a rotator or an isolator.

These devices offer:

• Specified performance to 400 W; tested to 1.2 kW
• Available with 5 mm, 8 mm, and 12 mm clear apertures
• Optimized for use from 1010 nm to 1080 nm
• Isolation greater than 33 dB
• Transmission greater than 95%
• Optional waveplates available

The Coherent PAVOS Ultra line of Faraday devices offers roughly 1/10th the absorption and thermal lens focal shift and can theoretically provide ten times lower non-linear refractive index compared to the standard PAVOS rotators and 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 400 W of average power.

Our PAVOS Faraday Rotators and Isolators are completely passive devices; no tuning required with a rugged design suitable for harsh operating environments. Optically contacted PBS cubes included for improved damage threshold. All isolators contain rejected beam escape ports and are adjustable to handle any angle of linear input polarization without additional optics. Precision mounting options and rejected beam pointing are available.
