Divided-Pulse Nonlinear Amplification at 1.5 μm

Divided-pulse nonlinear amplification was developed in the anomalous dispersion regime by combining the concepts of divided-pulse nonlinear amplification and divided-pulse compression. We realized compressor-free ultrafast pulse amplifiers at 1.5 μm with the help of simultaneous pulse amplification and compression in single-mode and few-mode fibers with anomalous dispersion. With optimized positiv...
