The unique wavelength-dependent resonance enhanced multiphonon ionization (REMPI) spectrum of a molecular species provides a means of selectively ionizing that particular species. Coupled with high sensitivity for the detection of any ions subsequent

Nuclear activation has been observed in materials exposed to energetic protons and heavy ions generated from high intensity laser-solid interactions (at focused intensities up to 5×1019 W/cm2). The energy spectrum of the protons is determined throug

The generation of MeV electron and ion beams using lasers with intensities of up to 1020 W cm-2 is reported. Intense ion beams with high energies (up to 40 MeV and to 3 × 1012 protons >5 MeV) are observed. The properties of these particle beams were

Protons of energies up to 37 MeV have been generated using ultra-intense laser-solid interactions. These protons can be used to induce nuclear reactions in materials to produce β+ emitting nuclei of relevance to the nuclear medicine community for Po

Novel measurements of electromagnetic radiation above 10 MeV are presented for ultra intense laser pulse interactions with solids. A bright, highly directional source of y rays was observed directly behind the target. The y rays were produced by brem

In the last decade the intensities of light fields which can be produced in a laser focus increased by four orders of magnitude from 1016 to 1020 W/cm2. Intensities exceeding 1018 W/cm2 allow for the production of relativistic laser plasmas, that is

Laser induced multiphoton ionization (MPI) has been used to produce positive and negative ions at atmospheric pressure in an ion mobility spectrometer. This paper deals particularly with the application of this technique to the ultra‐trace detectio
