Fig. 3: Scan rate and temporal resolution test.
a Agility in obtainable scan rates for lasers operating at the same, and different wavelengths. The lowered signal level at higher rates results from the lower number of coincidence/overlap events when a single IXC trace is produced. b Temporal resolution test that shows operation above the aliasing limit. A soliton triplet (triatomic molecule) is imaged. Even exceeding the aliasing limit almost 20 times still yields resolved pulses. Shown also is the power spectrum of the IXC signal, which is mostly concentrated in the low-frequency region rather than close to the Nyquist frequency fr/2. c 2+2 soliton molecular complex (SMC) probed by the IXC technique. The soliton pairs are separated by 88 ps, while the atom separation is 0.854 ns, which practically requires sub-GHz spectral resolutions to detect its presence. Such features are not resolved by a 50 pm (~6 GHz) resolution optical spectrum analyzer (OSA). Abbreviation: Rel. pow. — relative power.
