Fiber-to-Fiber Broadband Isolators - 40 W - Polarization Insensitive

EOT's 40 W Fiber-to-Fiber isolators are compact in size, light in weight, and employ EOT's proprietary Fiber Fuse End Cap Technology assuring high levels of reliability and resistance to damage. They also have a wide spectral range providing good isolation over the complete Yb+3 gain bandwidth. Because the input and output of these isolators are on the same end, they consume less space in a laser system. They can be easily placed in corners or other locations within a laser system where isolators having fiber on the input and output would not be practical. These isolators are ideally suited for separating amplifier stages in MOPA fiber lasers. They are designed for both CW and pulsed fiber lasers. Additionally, these isolators are avialable with ASE filters.
