Maximum intensity of the spectra recorded on the AILES beamline versus laser power for two focusing settings: (a) f# = 1.3 and (b) f# = 2.5. Spots for experimental data with (blue spots) 16.8 ≤ gap < 17 mm and (red dots) 17 ≤ gap < 17.5 mm. Lines for simulations using = 35 fs FWHM, ZR = 0.35 m at gap = 17 mm and an efficiency coefficient of (dotted line) 5, (full line) 10 and (dashed line) 15% on the laser power (i.e. for instance while 2 W are sent from the laser hutch, 2 W × 15% = 0.3 W are actually used for the simulation). |
