摘要
The influence of a frequency chirp induced in an excitation laser pulse by varying the second- and third-order group-delay dispersions with liquid-crystal spatial light modulators in a Fourier pulse shaper on the supercontinuum (SC) spectra generated from microstructured fibers is experimentally studied. In close-loop control experiments, an input laser pulse is adaptively shaped by referring to the SC spectrum. Optimum input laser pulse shapes for obtaining the highest power at one or two narrow bands in the SC spectrum are successfully obtained using a self-learning adaptive pulse shaping technique.
