“…For the case in which the proton beam is added, we find that the first few tens of microns depth from the front surface of the target is heated to temperatures of ∼10 eV, as shown in Figure 3(b), with an exponential decrease in temperature to about 0.3 eV at a depth of 100 µm. Similar laser-driven proton heating profiles have been reported in other work [18] . Importantly, we find that the target front side expands faster into vacuum in response to this heating, resulting in slightly larger plasma scale length, compared to the case of ASE-only heating.…”

The first experimental measurements of intense (∼7 × 10 19 W cm −2 ) laser-driven terahertz (THz) radiation from a solid target which is preheated by an intense pulse of laser-accelerated protons is reported. The total energy of the THz radiation is found to decrease by approximately a factor of 2 compared to a cold target reference. This is attributed to an increase in the scale length of the preformed plasma, driven by proton heating, at the front surface of the target, where the THz radiation is generated. The results show the importance of controlling the preplasma scale length for THz production.

“…Building on earlier proof of principle experiments on other laser systems [8,9] we have begun a campaign to study the equation of state (EOS) properties of a number of materials of interest in the temperature and density regime known as warm dense matter (WDM). Using a well-characterized, intense proton beam generated by petawatt laser-solid interaction with a source foil, a secondary sample foil is rapidly heated to temperatures of 1 to 100 eV.…”

“…Many experiments in the past have demonstrated that laser-accelerated ion beams provide high quality characteristics such as high particle intensities [1,2], short pulse lengths, and very low transverse source emittance [3] exceeding the parameters of standard particle accelerators. These qualities offer numerous potential applications reaching from ion sources of small dimensions over nuclear physics [4], high energy density physics like warm dense matter studies [5,6] as well as its diagnostics [7] and inertial confinement fusion [8,9] to medical applications like laser-induced proton therapy [10,11] in cancer treatment.…”

We report on the effects of fs-laser desorption on the ion acceleration induced by the target normal sheath acceleration (TNSA) mechanism. The experiment was performed at the Lawrence Livermore National Laboratory (LLNL) using the 100 TW Callisto laser of the Jupiter Laser Facility (JLF). Thin metal foils (Au, Cu, and Al) with thicknesses ranging from 10 to 20 m were irradiated by a variable number of low intensity ($ 10 12 W=cm 2 ) laser pulses, the last one arriving 100 ms before the main pulse. With these short pulses water vapor and hydrocarbon contaminations could stepwise be removed from the target surface. Substantial modifications of the TNSA-ion energy spectra were observed such as diminished proton energy and intensity, the absence of low-charged ion states, increased particle numbers for C 4þ and O 6þ ions in the higher energetic part of their particle spectra as well as the acceleration of target ions. The controlled application of fs-laser desorption on the laser-ion acceleration thus strongly influences the ion spectra and offers the possibility of selecting a targeted range of ion species for the acceleration to higher energies due to the systematic removal of contamination layers.
