Abstract
Vacuum-UV radiation from Xe jet-target laser-produced plasmas has been produced, spectrally dispersed, and efficiently focused onto a line-shaped interaction volume by adopting an embedded-in-the-chamber spectrograph geometry. Time-resolved 2D Rayleigh light scattering imaging has been carried out for visualizing the gas jet-laser plasma interaction and optimizing the emission intensity and the spectral resolution. We have calibrated the measured photon fluxes, reaching values higher than in the wavelength range within the first 20 ns from the laser pulse onset. The vacuum-UV light source is predicted to enable sensitive and selective single-photon ionization for time-of-flight mass spectrometry and similar vacuum-UV spectroscopy applications.
