PAVOS Rotators and Isolators
Achieve very high (≥30 dB) isolation for the pulsed or CW near-IR output from Nd- and Yb-based lasers, with PAVOS products optimized for the 1010 nm to 1080 nm window.
PAVOS Rotators and Isolators maximize the performance and eliminate ASE in your Nd or Yb amplified laser system and deliver protection from damaging back reflections. Several standard apertures plus custom apertures, mounting, and vacuum-compatible options on request.
PAVOS Rotators and Isolators - Key Parameters
Safely use any PAVOS Rotator or Isolator below the following damage thresholds: 10 J/cm² at 10 ns, 1 J/cm² at 8 ps, 1 MW/cm² CW. Wavelength range 1010 nm to 1080 nm.
