Extended Data Fig. 2: Observation of second plateau at 1,500 nm.
From: Multi-plateau high-harmonic generation in liquids driven by off-site recombination
Experimental HHG spectra from liquid D2O (a), H2O (b), ethanol (c) and isopropanol (d) at 1,500 nm driving wavelength, all showing second plateaus, indicating the generality of the phenomenon.
