Polarization roators offer 45° to 90°rotation at a number of common laser wavelengths.The optical axis in apolarization rotator is perpendicular to the polished face.The result is that the orientation of in put linearly polarized light is rotated as it propagates through the device.
Features:
Wide Angle Acceptance
Better Temperature Bandwidth
Wide Wavelength Bandwidth
AR Coated,R<0.2%
Fresnel Rhomb Retarders like broadband waveplates providing uniform λ/4 or λ/2 retardance over a wider range of wavelengths than possible with birefringent waveplates. They can replace retardation plates for broadband, multi-line or tunable laser sources.
The rhomb is designed so that a 45° phase shift occurs at each internal reflection creating a total retardance of λ/4. Because the phase shift is a function of the slowly varying rhomb dispersion, the retardance change with wavelength is mu...
TGG is an excellent magneto-optical crystal used in various Faraday devices (Rotator and Isolator) in the range of 400nm-1100nm, excluding 475-500nm.
Advantages of TGG:
Large Verdet constant (35 Rad T-1 m-1)
Low optical losses (<0.1%/cm)
High thermal conductivity (7.4W m-1 K-1).
High laser damage threshold (>1GW/cm2)

Erbium and ytterbium co-doped phosphate glass has a broad application because of the excellent properties. Mostly, it is the best glass material for 1.54μm laser due to its eye safe wavelength of 1540 nm and high transmission through atmosphere. It’s also suitable for medical applications where the need for eye protection may be difficult to manage or diminish or hinder essential visual observation. Recently it is used in optical fiber communication instead of EDFA for its more super pl...
Glan Taylor polarizer is made of two same birefringent material prisms that are assembled with an air space.Its length to aperture ratio which is less than 1.0 makes it a relatively thin polarizer.The polarizer with no side escape windows is suitable for low to medium power application where the side rejected beams are not required .The angular field of different materials of polarizers is listed below for comparison.
Feature:
Air-spaced
Close to Brewster’s Angle Cutting
