Control and characterization of soliton-like pulses in a femtosecond dye laser
The balance of positive self-phase modulation (SPM) and negative-group velocity dispersion (GVD) that enhances ultrashort pulse formation in a dispersion-compensated, colliding-pulse modelocked (CPM) dye laser was compared to the shaping mechanism for the N=1 soliton in an optical fiber. Periodic pulse shaping reminiscent of higher-order solitons has also been observed. It is however unclear how far the analogy in an optical fiber can be extended. Reported here are results of this investigation of periodic pulse shaping in a 7-mirror/4-prism CPM laser that delivers pulses as short as 35fs at 100 MHz. The stability achieved allows for reproducibility and full time-resolved characterization.
