PAVOS Ultra Rotators and Isolators


Optimized for high-power applications with Nd- and Yb-based amplifiers, these premium devices eliminate catastrophic whole beam self-focusing found with lower-grade materials and designs.

PAVOS Ultra Rotators and Isolators safely tolerate high laser power across the entire 1010 nm to 1080 nm window, where they eliminate damaging back-reflections. Several standard apertures plus custom apertures, mounting, and vacuum-compatible options on request.


PAVOS Ultra Rotators and Isolators - Key Parameters

Safely use any PAVOS Ultra Rotator or Isolator below the following damage thresholds: ≥6 J/cm² at 10 ns and ≥0.6 J/cm² at 8 ps minimum for PAVOS Ultra. Wavelength range 1010 nm to 1080 nm.
