HOLLOW-FIBER COMPRESSOR
Single-cycle hollow-fiber compressor: Measured (a) and retrieved (b) d-scan traces. (c) Measured spectrum (black) and retrieved spectral phase with standard deviation (red). (d) Retrieved temporal profile for the wedge insertion that minimizes the pulse duration, corresponding to 3.2 fs (1.3 cycles at 740 nm).
