Eurys Series 800 nm Broadband Optical Isolators for Ti:Sapphire Lasers - Small Aperture (5 mm)

EOT’s Eurys Series Broadband Faraday Rotators rotate the plane of polarized light 90° at 800nm in the forward direction and 0° from 720-950nm 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. A broadband optical isolator provides high transmission in the forward direction and strongly attenuates back-reflected light between 720-950nm 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.

**Please note that a waveplate is needed if you are wishing to achieve other than 90º rotation through the device.**

*If in Japan, please contact EOT directly for pricing and availability.

a Escape ports should be used if rejected light is >1W or 0.15J/cm² at 10ns or forward light is >25W. All stray beams should be properly terminated.


  • All products are RoHS compliant.
  • Product specifications and pricing subject to change without notice.
  • Operating Temperature: Performance of EOT’s Optical Isolators is related to operating temperature. For more information, please contact EOT.
  • Escape Ports: All EOT Broadband Optical Isolators come standard with double escape ports on both the input and output polarizer assemblies. These escape ports can be adjusted by the customer to be either open or closed. Escape ports should be used if rejected light is >1W or 0.15J/cm2 at 10ns or forward light is >25W. All stray beams should be properly terminated.. Failure to use the escape ports under these conditions could result in optical damage or degrade the performance of your isolator. Please consult EOT's User Guide on how to use the escape ports.
  • For incident powers ≥50W, you may contact EOT’s sales department at sales@eotech.com or view our Custom Products page on this website.
  • Dispersion: Some pulse broadening does occur when using EOT's Broadband Optical Isolator. The Sellmeiers Equation for TGG used in the broadband optical isolators is:
