摘要：
We report the construction of a cascaded fiber amplifier where a 40-pm-core-diameter photonic crystal fiber is utilized in the main amplifier stage. Single-transverse-mode, linearly-polarized, 7.5 ns pulses with 1.5 mi energy, 123 kW peak power and 10 nm spectral bandwidth centered at 1062 nm are generated. To our knowledge, the pulse energy we obtain is the highest from 40-mu m-core-diameter photonic crystal fibers, and also the highest for long pulses ( >1 ns) with linear polarization and single transverse mode.
