High Power Free Space and Fiber Pigtailed Isolators
Description
Isolators are optical devices that allow light to be transmitted in one direction only. They are most often used to prevent any reflected light from entering the source, thus preventing any feedback problems, such as frequency instability, relaxation oscillations, amplified stimulated emissions, or optical damage from occurring.
With the recent dramatic increase in laser output powers, especially in the 1030 to 1090nm wavelength range, the need to prevent the negative effects of optical feedback into lasers has become critical. To meet this demand OZ Optics has developed a line of high power handling polarization independent isolators, capable of peak isolation levels of 30 to 50dB for 1030 to 1090nm, depending on the input beam size. The isolators are offered with fiber pigtailed collimators on the input beam, with typical beam diameters of 0.4mm to 1.1mm.
