 Pavos Series 1010 nm - 1080 nm Faraday Rotators and Optical Isolators - Large Aperture (>5 mm) Data Sheet

Pavos Series 1010 nm - 1080 nm Faraday Rotators and Optical Isolators - Large Aperture (>5 mm)

EOT’s Pavos Series Faraday Rotators rotate the plane of polarized light 45° in the forward direction and an additional 45° of non-reciprocal rotation in the reverse direction while maintaining the light’s linear polarization. When placed between crossed polarizers, a Faraday rotator becomes an optical isolator. An optical isolator shields lasers from destabilizing and potentially destructive back-reflected light from interfaces on downstream optics or back-scattered ASE from optical amplifiers. Based on high Verdet constant, low absorption coefficient Terbium-based rotating material, and developed to work with up to 50 W of average input power in the 1µm wavelength range, Pavos Series optical isolators provide the ultimate protection for polarized output from Nd- or Yb-doped crystal, glass, and fiber lasers.

Benefits:

· Decouple Nd and Yb laser oscillators from ASE created by amplifiers

· Eliminate relaxation oscillations in mode-locked lasers due to optical feedback

· Eliminate frequency instability in seed sources

Features:                               

· All devices are completely passive, no tuning required

· All isolators contain escape ports; all rejected beams are deflected at 90°

· Optional λ/2 plate available for all isolators

Product specifications and pricing subject to change without notice.
Escape ports should be used if rejected light is >1 W or 0.15 J/cmat 10ns or forward light is >25 W. All stray beams should be properly terminated.
Note: All products are RoHS compliant.
