Method and light pulse source for generating soliton light pulses

摘要

A method of generating light pulses comprises providing pump laser pulses (1) with a pump laser source (10), coupling the pump laser pulses (1) into a pulse guiding medium (20) having an anomalous group-velocity dispersion and a Kerr nonlinearity, and propagating the pump laser pulses along the pulse guiding medium (20), wherein soliton-shaped light pulses are formed from the pump laser pulses within the pulse guiding medium (20) and, resulting from a photoionization of the pulse guiding medium (20) by the soliton-shaped light pulses, the soliton-shaped light pulses are subjected to a frequency shift towards higher spectral energies, wherein the method further includes setting the pump laser source (10) and the pulse guiding medium (20) such that the soliton-shaped light pulses are fundamental soliton light pulses (2) propagating in the pulse guiding medium (20), wherein the group-velocity dispersion of the pulse guiding medium (20) being selected such that a ratio of the group velocity dispersion and the power dependent Kerr nonlinearity decreases with increasing frequency and the fundamental soliton light pulses (2) are compressed simultaneously with the frequency shift. Furthermore, a light pulse source device (100) for generating compressed and frequency up-shifted light pulses is described.
