Figure 6: Auto-correlation traces and radio-frequency beating spectra of the realized pulses.
From: Multicolour nonlinearly bound chirped dissipative solitons

Traces are shown for DS (a) and RDS (b) after a double-pass compressor consisting of a grating pair. The compressor introduces one-pass group delay dispersion of D≈−0.7 ps2. Spectra measured at a repetition rate of 5 MHz with 1 Hz bandwidth (c), and at its 150th harmonic (750 MHz) with 1 kHz bandwidth (d).
