“…In striking contrast, the application of the mixed XUV/Vis-NIR field resulted in clearly visible, irreversible surface modification after irradiation with only a few shots. The damage is characteristic due to material expansion, quite different from ablation craters observed in experiments with pure XUV pulses (Chalupsky et al, 2007;Juha et al, 2005;Vaschenko et al, 2006;Krzywinski et al, 2007;Mocek et al, 2006). A very interesting feature in Fig.…”

“…Such lasers can enable fundamental studies and be utilized for applications such as nanomachining 14,15 and the development of nanoprobes. [16][17][18] We present the results of experiments undertaken with an argon capillary discharge laser, producing nanosecond pulses at a wavelength of 46.9 nm, focused onto thin parylene-N targets.…”

An optimized focused ion beam process is used to fabricate micrometer-long LiNbO3 nanopillars with diameters varying between 150 and 325 nm. Polarimetric mappings of second harmonic generation from a wavelength of 850 nm demonstrate the ability to modify the polarization features of the nonlinear response through a fine adjustment of the pillar size. The effect is ascribed to the non-negligible contribution of the longitudinal fields associated with sub-wavelength light confinement in the LiNbO3 nanopillars. The results also highlight the importance of a fine control over the nanopillar size in order to effectively engineer their nonlinear response.

“…Considerable advances have been made in higher fluence EUV and x-ray laser technology as demonstrated by free-electron lasers [1,2] and capillary discharge lasers [3,4]. With higher fluences now available, EUV and x-ray lasers can be used to directly generate strongly coupled plasma.…”

Argon based capillary discharge lasers operating in the extreme ultra violet (EUV) at 46.9 nm output up to 0.5 mJ energy per pulse at up to 10 Hz repetition rates are capable of focussed irradiances of 10 9 -10 12 W cm −2 and can be used to generate plasma in the warm dense matter regime by irradiating solid material. To model the interaction between such an EUV laser and solid material, the 2D radiative-hydrodynamic code POLLUX has been modified to include absorption via direct photo-ionisation, a super-configuration model to describe the ionisation dependant electronic configurations and a calculation of plasma refractive indices for ray tracing of the incident EUV laser radiation. A simulation study is presented, demonstrating how capillary discharge lasers of 1200 ps pulse duration can be used to generate warm dense matter at close to solid densities with temperatures of a few eV and energy densities up to 1 × 10 5 J cm −3 . Plasmas produced by EUV laser irradiation are shown to be useful for examining the properties of warm dense matter as, for example, plasma emission is not masked by hotter, less dense plasma emission as occurs with visible/infra-red laser target irradiation.
