Web19 Apr 2024 · High harmonic generation (HHG) enables coherent extreme-ultraviolet (XUV) radiation with ultra-short pulse duration in a table-top setup. This has already enabled a plethora of applications. Nearly all of these applications would benefit from a high photon flux to increase the signal-to-noise ratio and decrease measurement times. In addition, … WebThe shortest pulse obtained from a dye laser, 6 fs, has been reported by Fork and colleagues, in 1987, using extra-cavity compression. In that experiment, a dye laser incorporating CPM …

Web22 Nov 2024 · The experiments were conducted using the “Pulsar” Ti:sapphire laser (wavelength λ 1 = 800 nm) at Shanghai Jiao Tong University. Figure 1 schematically shows the setup; laser pulses with energy of 2.1 J and duration of 30 fs are split into a driver beam (E 1 = 1.9 J) and another beam (E 2 = 0.2 J) by a 25-mm-diameter dielectric mirror, which … Web(pulse length 20 fs, spot size 28 mm) with a 7 mm long gas-jet with a plasma density of 3 1018 cm 3. During propagation in the plasma the high-intensity laser pulse excites a bubble wake where electrons are self-injected [15]. Due to the relatively high bunch charge (120 pC) and very short bunch (9 fs FWHM), the normalized transverse table of tense changes in reported speech
