Zusammenfassung: | Results of experimental and numerical investigation of supercontinuum generation in polarization maintaining photonic crystal fiber using a burst of two orthogonal polarization femtosecond pump pulses are presented. The initial pump pulse source was a mode-locked Yb:KGW laser generating 52 nJ energy 90 fs duration pulses at 1033 nm with 76 MHz repetition rate. Analysis of cross-correlation frequency-resolved optical gating traces and numerical simulation results reveal that there are slight changes in supercontinuum generation when temporal delay between pump pulses in the burst is changed. Weak dependence of supercontinuum characteristics on temporal distance between the pump pulses is related to supercontinuum generation dynamics which is analyzed in detail.
•Supercontinuum generation in highly nonlinear PM PCF is investigated.•The pump source is a controlled burst of two femtosecond pulses (λc=1033nm).•XFROG technique was used to investigate supercontinuum temporal characteristic.•Experimental investigation shows slight changes in supercontinuum characteristics.•Numerical simulation results are in good qualitative agreement with experiment. |
