    Fiber coupling - SmartDock
    Especially designed for the iBeam smart TOPTICA's SmartDock turns the iBeam smart into a rugged fiber coupled diode laser system. Both single-mode and polarization-maintaining fibers can be connected to the SmartDock. Better than 60 % coupling efficiency is guaranteed but efficiencies up to 90 % have been demonstrated due to the high beam quality of the iBeam smart.
