    We investigate the excitation of coherent acoustic and optical phonons by ultrashort extreme ultraviolet (EUV) pulses produced by a free electron laser. Two crossed femtosecond EUV (wavelength nm) pulses are used to excite coherent phonons at a wavelength of nm, which are detected via diffraction of an optical probe : A. A. Maznev, F. Bencivenga, A. Cannizzo, F. Capotondi, R. Cucini, R. A. Duncan, T. Feurer, T. D. Fr. Prebunching is an effective technique to reduce the radiation saturation length and to improve the longitudinal coherence and output stability in storage-ring-based free-electron lasers (FELs). A novel technique is proposed which uses angular dispersion to enhance the high-harmonic bunching with very small laser-induced energy by: 2.

    Extreme-ultraviolet vortices may be exploited to steer the magnetic properties of nanoparticles, increase the resolution in microscopy, and gain insight into local symmetry and chirality of a material; they might even be used to increase the bandwidth in long-distance space communications. However, in contrast to the generation of vortex beams in the infrared and .   A high-gain harmonic-generation free-electron laser is demonstrated. Our approach uses a laser-seeded free-electron laser to produce amplified, longitudinally coherent, Fourier transform–limited output at a harmonic of the seed laser. A seed carbon dioxide laser at a wavelength of micrometers produced saturated, amplified free-electron laser output at Cited by:

Applied Physics Letters, Vol.Issue. 22, p. 6 - X-Ray and EUV Free Electron Lasers pp Get by:   We investigate the excitation of coherent acoustic and optical phonons by ultrashort extreme ultraviolet (EUV) pulses produced by a free electron laser.

Two crossed femtosecond EUV (wavelength nm) pulses are used to excite coherent phonons at a wavelength of nm, which are detected via diffraction of an optical probe by: 5. Single-pass free-electron lasers based on self-amplified spontaneous emission are enabling the generation of laser light at ever shorter wavelengths, including extreme ultraviolet, soft X-rays and even hard X-rays.

A typical X-ray free-electron laser is a few kilometres in length and requires an electron-beam energy higher than 10 GeV (refs 6, 8).Cited by: Several current and next generation free-electron laser (FEL) facilities provide fully coherent pulses with few femtosecond pulse durations and extreme ultraviolet (XUV) photon energies.

generation of vortex beams in the infrared and visible spectral regions, production of intense, extreme-ultraviolet and x-ray optical vortices still remains a challenge. Here, we present an in-situ and an ex-situ technique for generating intense, femtosecond, coherent optical vortices at a free-electron laser in the extreme ultraviolet.

"There has been a remarkable improvement in capabilities for probing matter with x-rays and extreme ultraviolet (EUV) radiation since the previous edition of this book appeared in The spectral brightness and coherence of available research facilities has increased by many orders of magnitude across the EUV and x-ray spectral regions, extending from photon 5/5(1).

Coherent extreme-ultraviolet emission can be obtained through high-harmonic generation and multiphoton excitation from atoms exposed to a strong laser field.

We report the generation of a new kind of coherent extreme-ultraviolet emission from He atoms excited by intense few-cycle laser by: 8. FLASH is a SASE FEL that produces EUV radiation during a single pass of an electron beam through a long periodic magnetic undulator.

The driving mechanism of a FEL is the radiative instability of the electron beam due to the collective interaction of electrons with the electromagnetic field in the by: With the recent experiments done at the FERMI free-electron laser facility in Trieste we demonstrated the capability of the used method to produce highly coherent pulses allowing to improve the performances of FELs in the EUV spectral range overcoming some of the limitations that are typical of systems based on the self amplified spontaneous emission (SASE).Author: E.

After a brief introduction to how FELs fit in with other sources of coherent radiation and how FEL amplification can work, we derive in Section the 1D equations of Author: Kwang-Je Kim, Zhirong Huang, Ryan Lindberg. Recent development of free‐electron laser (FEL) component technologies should enable these devices to operate in the extreme‐ultraviolet, well below nm.

When fully developed, FELs represent the next generation of coherent‐radiation sources with peak‐ and average‐power outputs surpassing those of any existing, continuously tunable photon source Cited by: 2.

Topical Meeting on Free Electron Generation of Extreme Ultraviolet Coherent Radiation.

By J M J Madey and Claudio Pellegrini. Topics: Other Fields of Physics. Publisher: AIP. Year: OAI identifier: oai: Provided by: Author: J M J Madey and Claudio Pellegrini. Extreme ultraviolet radiation or high-energy ultraviolet radiation is electromagnetic radiation in the part of the electromagnetic spectrum spanning wavelengths from nm down to 10 nm, and therefore having photons with energies from 10 eV up to eV.

EUV is naturally generated by the solar corona and artificially by plasma and synchrotron light sources. Since UVC extends to nm, there is some overlap in the terms. The main uses of extreme. Free-electron lasers are radiation sources, based on the coherent emission of synchrotron radiation of relativistic electrons within an undulator or wiggler.

The resonant radiation wavelength. Coherent extreme-ultraviolet (EUV) radiation produced by means of high-order harmonics generation (HHG) from intense laser pulses is used for various ultrafast pump–probe experiments.

In this study, we test bulk sapphire as to its HHG capability as a new solid EUV emitter operating with moderate nJ-energy laser pulses obtained directly from an by:   The study of free electron lasers for use on sufficient single pass gain is outlined, the availability of mirrors of high reflectance, however, for the vacuum ultraviolet and soft X-ray regime make resonant cavities a possibility.

As in ordinary synchrotron radiation work, mirrors are required for the construction of realistic experiments and for beam manipulation purposes Cited by: 4. Bartels et al., "Generation of Spatially Coherent Light at Extreme Ultraviolet Wavelengths", Science().

Using a focussed narrow-bandwidth high harmonic generation (HHG) source with wavelength around 30 nm we achieve a resolution of ∼45 nm with a sample size down to 3 μm Cited by: 2.The book reviews the most recent achievements in optical technologies for XUV and X-ray coherent sources.

Particular attention is given to free-electron-laser facilities, but also to other sources available at present, such as synchrotrons, high-order laser harmonics and X-ray lasers.Here, we propose an echo-enabled harmonic generation (EEHG)-technique-based free electron laser (FEL) scheme that uses a low-energy beam (K E ∼ MeV).

The proposed scheme is designed to generate short-pulse soft extreme ultraviolet radiation at ∼ 80 nm, with a pulse duration of 3 fs for the full width at half : Ji-Gwang Hwang, Eun-San Kim.
