Physical Sciences Inc. (PSI), has been awarded a contract from the U.S. Air Force to develop a high power fiber-based optical isolator operating at a wavelength of 2 microns.
Advancements in high-energy pulsed fiber lasers have a broad impact on defense and industrial applications. In particular, 2 micron fiber amplifiers demonstrate great promise for improved scalability, nonlinear performance, efficient thermal management, and atmospheric transmission. Optical isolators are the key component in laser systems that protect them from unwanted, back-reflected light, which can act to destabilize or even damage the system. Currently, commercially available optical isolators are not suitable for high-power pulsed fiber amplifiers at 2 micron.
Physical Sciences Inc. proposes to develop a novel 2 µm fiber optical isolator based on a design tailored for high average and peak powers. The developed optical isolator will be able to handle average power of 100 W and peak power of 100 kW while maintaining beam quality and providing high optical isolation.
