500 W Fiber to Free Space Isolator

GKER’s High Power Fiber to Free Space Isolator (HPFSI) is the best choice for high power industrial pulse fiber lasers. A newly designed isolator can handle 500W average laser power and at competitive cost. It also can integrated with GKER’spatented SteadiBeamTM and SeasonBeamTM technologies to achieve thermal lensing-free beam quality and temperatureinsensitive high isolation.
