K-shell x-ray emission enhancement via self-guided propagation of intense laser pulses in Ar clusters.
نویسندگان
چکیده
K-shell x-ray at about 3 keV emitted from Ar clusters irradiated by 110 mJ 55 fs intense laser pulses is studied. The x-ray flux is optimized by moving the nozzle away from the focus of the laser pulse. The total flux of K-shell x-ray photons in 4pi reaches a maximum of 4.5x10(9) photons/shot with a conversion efficiency of 2.5x10(-5) when the nozzle displacement is 2 mm and a long plasma channel is observed by a probe beam.

Observation of subpicosecond x-ray emission from laser-cluster interaction.
We present the first experimental evidence of the subpicosecond duration of x-ray pulses emitted from laser-irradiated clusters, demonstrating the suitability of such a debris free target for ultrafast x-ray science applications. The K-shell emission (approximately 3 keV) from large Ar clusters (6 x 10(5) to 4 x 10(6) atoms) is time resolved, when irradiated by ultrashort (40 fs to 5 ps) and in...
متن کاملInvestigation of laser-irradiated Ar cluster dynamics from K-shell x-ray emission measurements.
Intense (up to a few 10(17) W/ cm2) femtosecond (down to 40 fs) laser pulses are focused onto a partially clusterized argon gas jet. The target was previously characterized and optimized in order to get a homogeneous and dense jet of clusters with a well controlled size. The interaction leads to x-ray emission that is absolutely calibrated and spectrally resolved using a high resolution time-in...
متن کاملIntense high-contrast femtosecond K-shell x-ray source from laser-driven Ar clusters.
Bright Ar quasimonochromatic K-shell x ray with very little background has been generated using an Ar clustering gas jet target irradiated with a 30 fs ultrahigh-contrast laser, with a measured flux of 2.2×10(11) photons/J into 4π. This intense x-ray source critically depends on the laser contrast and intensity. The optimization of source output with interaction length is addressed. Simulatio...
متن کاملCorrelated electronic decay in expanding clusters triggered by intense XUV pulses from a Free-Electron-Laser
Irradiation of nanoscale clusters and large molecules with intense laser pulses transforms them into highly-excited non- equilibrium states. The dynamics of intense laser-cluster interaction is encoded in electron kinetic energy spectra, which contain signatures of direct photoelectron emission as well as emission of thermalized nanoplasma electrons. In this work we report on a so far not obser...
متن کاملCharge recombination in soft x-ray laser produced nanoplasmas
The ionization and charge separation processes of nanoplasmas created by resonant excitation of atomic clusters in intense soft x-ray pulses have been investigated. Through irradiation with femtosecond pulses from the FLASH free electron laser (FEL) at λ = 13.7 nm and power densities exceeding 1014 W cm−2 the clusters are highly ionized with transient atomic charge states up to 9+. Variation of...
