55. Increasing the brightness of harmonic XUV radiation with spatially-tailored driver beams.

Abstract

Bright high harmonic sources can be produced by loosely focussing high peak power laser pulses to exploit the quadratic scaling of flux with driver spot size at the expense of a larger experimental footprint. Here, we present a method for increasing the brightness of a harmonic source (while maintaining a compact experimental geometry) by spatially shaping the transverse focal intensity distribution of a driving laser from a Gaussian to supergaussian. Using a phase-only spatial light modulator we increase the size and order of the supergaussian focal profiles, thereby increasing the number of harmonic emitters more efficiently than possible with Gaussian beams. This provides the benefits of a loose focussing geometry, yielding a five-fold increase in harmonic brightness, whilst maintaining a constant experimental footprint. This technique can readily be applied to existing high harmonic systems, opening new opportunities for applications requiring bright, compact sources of coherent short wavelength radiation.

Abstract

International audience; An experimental demonstration of an optical field ionization short-wavelength laser driven in a gas-filled capillary-discharge waveguide is described in detail. Guiding of high-intensity laser pulses has previously been demonstrated with this type of waveguide for capillary discharges in hydrogen. For the present experiments xenon gas was mixed with the hydrogen, and strong lasing on the 4d^95d-4d^95p transition in Xe8+ at 41.8 nm was observed. Under optimum conditions the short-wavelength laser output achieved with the waveguide was found to be greater than that from a Xe gas cell. Measurements of the transmission of the pump laser pulses through the waveguide show that the short-wavelength laser signal was greatest under conditions for which the pump laser pulses were well guided. Simulations of the propagation of the pump laser radiation are presented for a range of initial plasma conditions, and these indicate that the laser-plasma interaction length achieved was greatly increased compared to that which can be achieved in a gas cell.

Abstract

Synchrotrons and free-electron lasers (FELs) are the most powerful sources of Xray radiation. They constitute invaluable tools for a broad range of research in physics, biology, materials science, chemistry, and medicine. However, their dependence on large-scale radio-frequency electron accelerators restricted diversification of these X-ray sources to only several sites worldwide. Laser-driven plasma-wave accelerators provide dramatically increased accelerating fields and hence offer the potential to shrink the size and cost of these X-ray sources to the university-laboratory scale. Here we demonstrate the generation of soft-X-ray undulator radiation with laser-plasma-accelerated electron beams. The wellcollimated beams deliver soft-X-ray pulses with an expected pulse duration of ~10 fs, inferred from the physics of plasma-wave accelerators. Our source draws on a dedicated 30-cm-long undulator and a 1.5-cm-long accelerator delivering stable electron beams5 with energies of ~210 MeV. The spectrum of the generated undulator radiation typically consists of a main peak centered at a wavelength of ~18 nm (fundamental), a second peak near ~9nm (second harmonic) and a highenergy cutoff at ~7 nm. Magnetic quadrupole lenses ensure efficient electron beam transport and demonstrate an enabling technology for reproducible generation of tunable soft-X-ray undulator radiation. The source is scalable to shorter wavelengths by increasing the electron energy. Our results open the prospect of brilliant, ultrashort-pulsed X-ray sources becoming available in smallscale laboratories

Abstract

Laser-driven, quasi-monoenergetic electron beams of up to ~200 MeV in energy have been observed from steady-state-flow gas cells. These beams emitted within a low-divergence cone of 2.1± 0.5 mrad FWHM display unprecedented shot-to-shot stability in energy (2.5% RMS), pointing (1.4 mrad RMS) and charge (16% RMS) owing to a highly reproducible gas-density profile within the interaction volume. Laser-wakefield acceleration in gas cells of this type provides a simple and reliable source of relativistic electrons potentially suitable for applications such as the production of XUV-undulator radiation.

Abstract

We report experimental results on laser-driven electron acceleration with low divergence. The electron beam was generated by focussing 750-mJ, 42-fs laser pulses into a gas-filled capillary discharge waveguide at electron densities in the range between 1018 cm−3 and 1019 cm−3. Quasi-monoenergetic electron bunches with energies as high as 500 MeV have been detected, with features reaching up to 1 GeV, albeit with large shot-to-shot fluctuations. A more stable regime with higher bunch charge (20-45 pC) and less energy (200-300 MeV) could also be observed. The beam divergence and the pointing stability are around or below 1 mrad and 8 mrad, respectively. These findings are consistent with self-injection of electrons into a breaking plasma wave.

Abstract

This paper describes an experiment to demonstrate for the first time, laser wakefield acceleration (LWFA), driven by 1O.6-micrometer light from a CO2 laser. This experiment is also noteworthy because it will operate in a pseudoresonant LWFA regime in which the laser-pulse-length is too long for resonant LWFA, but too short for self-modulated LWFA. Nonetheless, high acceleration gradients are still possible. This experiment builds upon an earlier experiment called staged electron laser acceleration (STELLA) where efficient trapping and monoenergetic laser acceleration of electrons were demonstrated using inverse free electron lasers. The aim is to apply the STELLA approach of laser-driven microbunch formation followed by laser-driven trapping and acceleration to LWFA. These capabilities are important for practical electron linear accelerator based upon LWFA., Published in IEEE Transactions on Plasma Science, v33 n1 p3-7, February 2005.
