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 50W 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.

Features: Power handling up to 400 W* All devices are passive; no tuning required All isolators contain escape ports for

rejected beam(s) Polarizing beam splitter cube polarizers

result in no beam offset

a Product specifications are subject to change. b 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 proper-ly terminated. c At customer-specified wavelength and temperature d Input cube only Note: All products are RoHS compliant. * For powers higher than 400 W, contact EOT.

Benefits: Significantly reduced thermal lens focal shift at

>100 W reduces the need for additional optics to optimize spot size and significantly reduces the range of thermal lens focal shift as the laser power is varied

Lower thermal birefringence resulting in higher isolation at >100 W enables the use of higher gain amplifiers and in some cases may eliminate the need for a second isolator

Greater flexibility in design with respect to B integral due to lower nonlinear refractive index

EOT’s Makros 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 rotating material, and developed to work with up to 30W of average input power in the 1900-2000nm wavelength range, Makros Series optical isolators provide the ultimate protection for polarized output from Ho and Tm lasers.

Eurys Series - Small Aperture (5mm) Broadband Faraday Rotators and Isolators for Ti:Sapphire Lasers

EOT’s Eurys Series Broadband 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. Eurys Series broadband optical isolators provide 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 las-ing 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.

EOT’s Tornos 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 provides high transmission in the forward direction and strongly attenuates any light traveling in the reverse direction, effectively protecting laser diodes from the deleterious effects of back reflections. Tornos Series optical isolators can be ordered with dichroic glass polarizers to minimize the size of the device for low power applications or they can be ordered with polarizing beam splitter cube polarizers for applications where maximum transmission is required and power levels do not permit the use of dichroic glass polarizers. By aligning the output polarizer orthogonal to the backward traveling light, isolation can be maximized within the usable wavelength range of the optical isolator.
