Femtosecond laser pulse shaping for enhanced ionization
We demonstrate how the shape of femtosecond laser pulses can be tailored in order to obtain maximal ionization of atoms or molecules. For that purpose, we have overlayed a direct-optimization scheme on top of a fully unconstrained computation of the three-dimensional time-dependent Schrödinger equation. The procedure looks for pulses that maintain the same total length and integrated intensity ...
متن کاملExperiments on Microwave Scattering of REMPI in Argon, Xenon and Nitric Oxide
Experiments on microwave scattering from resonance enhanced multiphoton ionization (RADAR REMPI) are presented for argon (3+1 REMPI), xenon (2+1 REMPI) and nitric oxide (1+1 REMPI) to demonstrate its capabilities for nonintrusive diagnostics. The time evolution of the microwave scattering from 3+1 REMPI in argon with different frequency tripled Ti:sapphire laser pulse energies at different pres...
متن کاملTowards Xenon Neutral Density Measurements Using Radar REMPI Radar REMPI is a microwave-scattering-based resonance-enhanced multiphoton ionization
Radar REMPI is a microwave-scattering-based resonance-enhanced multiphoton ionization diagnostic technique [1] which has been applied to detect trace species in air [2], measure electron loss rates [3], and measure temperature in gas mixtures and flames [4]. The resonance enhanced technique provides high selectivity in measuring species of interest, and hence can be used to measure the density ...
متن کاملProgress of resonant ionization laser ion source development at GANIL.
SPIRAL2 (Système de Production d'Ions Radioactifs Accélérés en Ligne) is a research facility under construction at GANIL (Grand Accélérateur National d'Ions Lourds) for the production of radioactive ion beams by isotope separation on-line methods and low-energy in-flight techniques. A resonant ionization laser ion source will be one of the main techniques to produce the radioactive ion beams. G...
متن کاملREMPI Spectroscopy of Laser Desorbed Guanosines.
To observe fundamental properties of DNA building blocks it is desirable to study individual nucleosides in the gas phase without interference from solvent molecules, or macromolecular structure. As a first step, we have recently reported the first vibronic spectrum of the nucleobase guanine, obtained by a combination of laser desorption, jet cooling, and resonance enhanced multiphoton ionizati...
