Bend distortion in large mode area fiber amplifiers

As ever larger mode area fibers are designed and incorporated into high-power amplifiers, bend-induced mode distortion becomes an important limitation. In any reasonable coiled-fiber arrangement, bend distortion can reduce mode area, gain interaction, and suppression of higher-order modes. These imp...

Summary:As ever larger mode area fibers are designed and incorporated into high-power amplifiers, bend-induced mode distortion becomes an important limitation. In any reasonable coiled-fiber arrangement, bend distortion can reduce mode area, gain interaction, and suppression of higher-order modes. These impacts are reviewed, along with design strategies with increased immunity to bend distortion.
