“…In the present study, not only the laser wavelength is short ͑Ͻ100 nm͒ but also the pulse duration is very short ͑fluctu-ates within 30-150 fs͒. 6 The short-wavelength and ultrafast coherent beam represents a unique combination. The ablation behavior of a wide variety of materials has been investigated under these irradiation conditions.…”

The results of a study of irreversible changes induced at surfaces of metals, semiconductors, and insulators by extreme ultraviolet ͑ Ͻ100 nm͒ ultrashort pulses provided by TESLA Test Facility Free-Electron Laser, Phase 1 ͑TTF1 FEL͒ are reported and discussed. The laser was tuned at 86, 89, and 98 nm during the experiments reported here. Energy spectra of ions ejected from the irradiated surfaces are also reported. Special attention is paid to the difference in the ablation behavior of ͑semi͒conductors and insulators that we have observed. The difference is dramatic, while the absorption coefficients are similar for all materials at the TTF1 FEL wavelength.

“…In September 2000, a group at Argonne National Laboratory (ANL) became the first to demonstrate saturation in a visible (390 nm) SASE FEL (11). Soon after, in September 2001, a group at DESY (Hamburg, Germany) demonstrated lasing to saturation deep into the vacuum-UV at 98 nm (12,13). Since August 2005 the latest generation SASE FEL FLASH (Free Electron Laser in Hamburg) has been operating as a user facility (14) providing radiation at a fundamental wavelength which can be tuned from 47 nm down to 13 nm.…”

“…The primary interaction is with inner shell electrons and so EUV laser matter interactions will be a rich vein of new science and applications in the coming decade. The first experimental results demonstrating the ability of future XFELs to generate pulses of a few tens of femtoseconds have been achieved recently at FLASH (12)(13)(14).…”

We report recent results on the performance of FLASH (Free Electron Laser in Hamburg) operating at a wavelength of 13.7 nm where unprecedented peak and average powers for a coherent EUV radiation source have been measured. In the saturation regime the peak energy approached 170 µJ for individual pulses while the average energy per pulse reached 70 µJ. The pulse duration was in the region of 10 femtoseconds and peak

FLASH at DESY, Hamburg, Germany is the first free-electron laser (FEL) operating in the extreme ultraviolet (EUV) and soft x-ray wavelength range. FLASH is a user facility providing femtosecond short pulses with an unprecedented peak and average brilliance, opening new scientific opportunities in many disciplines. The first call for user experiments has been launched in 2005. The FLASH linear accelerator is based on TESLA superconducting technology, providing several thousands of photon pulses per second to user experiments. Probing femtosecond-scale dynamics in atomic and molecular reactions using, for instance, a combination of x-ray and optical pulses in a pump and probe arrangement, as well as single-shot diffraction imaging of biological objects and molecules, are typical experiments performed at the facility. We give an overview of the FLASH facility, and describe the basic principles of the accelerator. Recently, FLASH has been extended by a second undulator beamline (FLASH2) operated in parallel to the first beamline, extending the capacity of the facility by a factor of two.
