Figure 3: Experimental and theoretical pump–probe data in the time domain.
From: Long-term mutual phase locking of picosecond pulse pairs generated by a semiconductor nanowire laser
Time-dependent emission of the NW laser as a function of Δt after Fourier transforming the optical spectra. The data are plotted on a logarithmic colour scale that spans two orders of magnitude. (a) Pump pulse in the lasing regime and probe pulse in the spontaneous emission regime (pump pulse power Ppump∼5 × Pth and probe pulse power Pprobe∼0.6 × Pth). (b) Pump and probe pulse in the lasing regime (L-L)—(Ppump∼5 × Pth and Pprobe∼4.7 × Pth).
