Protontherapy is a well-established approach to treat cancer due to the favorable ballistic properties of proton beams. Nevertheless, this treatment is today only possible with large scale accelerator facilities which are very difficult to install at

Using the technique of frequency-domain interferometry, we study the dynamics of ultrafast laser-produced plasmas at moderate laser irradiances. From the complex reflection coefficient measured with the two in-quadrature probe pulse polarizations, we

Using the technique of frequency-domain interferometry, we demonstrate a new way of studying laser-induced breakdown at the surface of dielectric materials. A theoretical model based on electron production by multiphoton ionisation, inverse bremsstra

We describe the design and operation of a 2-stage multi-pass Ti:sapphire amplifier laser system, which is optimised for a broad transmission bandwidth and incorporates a novel reflective spherical mirror pulse-stretcher. Output energies of 180 mJ aft

We report on background-free intensity autocorrelation studies of sub-50 fs pulses from a Kerr lens mode-locked (KLM) Ti: sapphire laser over an intensity dynamic range of approximately 7 orders of magnitude. Results reveal the presence of a low inte

Rationale and Objectives. Relatively disappointing results with continuous-wave lasers stimulated us to evaluate pulsed lasers for interventional radiology. In this article, we describe our efforts to assess the effects of this technology ex vivo. Me

We have studied the doubly charged ion yields and electron energy spectra (normal and coincidence) for double ionization of atoms in two different ionization regimes (perturbative and tunneling). In both cases, the double-ionization rates appear to b

Electron energy spectra from ionization of the noble gases by 617-nm, 100-fs intense laser pulses show that the periodical double structure of narrow Stark-induced resonances and above-threshold ionization disappears gradually from xenon to helium. T

Ultrafast reaction dynamics of nonequilibrium electronic states in pure liquid water (D 2 O vs H 2 O) have been investigated using ultraviolet femtosecond laser pulses and time-resolved spectroscopy in the visible and near infrared regions. In pure l

Infrared femtosecond pulses of 100 μJ of energy are generated in a two-stage, triple-pass, type I β-barium borate parametric amplifier. A focusable intensity of 5 × 1012 W/cm2 with an f/20 optic is demonstrated.
