EURYS Broadband Optical Isolators - 720 nm to 950 nm
EOT's EURYS Broadband Rotators rotate the plane of polarized light 90° at 800 nm in the forward direction and 0° from 720 nm to 950 nm in the reverse direction while maintaining the light's linear polarization. When placed between crossed polarizers, a broadband Faraday rotator becomes a broadband optical isolator.
EURYS Broadband Optical Isolators provide high transmission in the forward direction and strongly attenuate back-reflected light between 720 nm to 950 nm in the reverse direction protecting Ti:Sapphire oscillators from the deleterious effects of back reflections and also eliminating preferential lasing at the lower gain wavelengths of Ti:Sapphire lasers. Utilizing optics with low refractive indices and short optical pathlengths minimizes pulse broadening due to dispersion in the optics associated with ultra-short laser pulses.

Product specifications are subject to change. All products are RoHS compliant.
a Escape ports should be used if rejected light is >1 W or 0.15 J/cm2 at 10 ns or forward light is >25 W. All stray beams should be properly terminated.
Dispersion: Some pulse broadening does occur when using EOT's EURYS Broadband Isolators. The Sellmeiers Equation for TGG used in the broadband isolators is:
