1050 nm - 1080 nm Low Power Optical Isolators

EOT's 1050-1080nm Low Power 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 seed sources from the deleterious effects of back reflections. EOT's 1050-1080nm Low Power Optical Isolators can be ordered with either dichroic glass polarizers or with polarizing beam splitter cubes. If protecting a seed source from back reflections from a Q-switched laser, EOT recommends using polarizing beam splitter cubes due to their ability to withstand high pulse energies. Two isolators can be used in series for 60dB isolation is required to assure back reflections do not cause frequency instability from a single frequency single seed laser.
