Segmented cladding fiber design for femtosecond laser pulse delivery at 1550-nm and 1064-nm wavelengths

摘要

We numerically demonstrate near distortion-free propagation of 100-fs, over 50-kW peak power pulses at 1550-nm wavelength with 1825-μm² mode area, and 250-fs, 15-kW pulses at 1064-nm wavelength with 1800 μm² mode area, through segmented cladding fiber.
