Abstract (EN):
Intense few- and single-cycle pulses are powerful tools in different fields of science Today, third-and higher-order terms in the remnant spectral phase of the pulses remain a major obstacle for obtaining high-quality few-and single-cycle pulses from in-line post-compression setups. In this Letter, we show how input pulse shaping can successfully be applied to standard post-compression setups to minimize the occurrence of high-order phase components during nonlinear propagation and to directly obtain pulses with durations down to 3 fs. Furthermore, by combining this pulse shaping of the input pulse with new-generation broadband chirped mirrors and material addition for remnant third-order phase correction, pulses down to 2.2 fs duration have been measured.
