Nonlinear pulse compression in a dispersion-alternating fiber (Conference Presentation)
Author(s): Niklas M. Lüpken; Carsten Fallnich

Paper Abstract

A concept for nonlinear pulse compression is presented, which relies on alternating the dispersion sign by repeatedly splicing segments of normal to anomalous dispersion fibers. This approach accomplishes to limit temporal defocusing by repetitive recompression of the broadened bandwidth, resulting in few-cycle pulses without the need of soliton formation or free-space compressors. We show the compression of 80 fs pulses down to 25 fs pulses, which are nearly bandwidth-limited by using a special dispersion compensating fiber. Besides further scaling of pulse duration, we show a stability and scaling analysis regarding the input conditions and the highly coherent few-cycle output.
