چکیده

We report the first demonstration of soft x-ray amplification in an elongated plasma column produced by laser irradiation of a gas puff target. The gas puff target is formed by the pulsed injection of gas from a high-pressure solenoid valve through a nozzle in the form of a narrow slit. The plasma column to be used as an x-ray laser active medium is produced by irradiating the gas puff target with a highpower laser beam focused to a line. Lasing in neonlike argon at 46.9 nm and strong indications of lasing in nickel-like xenon at 10.0 nm were observed.

Short-wavelength ablation of polymers in the high-fluence regime

Short-wavelength ablation of poly(1,4-phenylene ether-ether-sulfone) (PPEES) and poly(methyl methacrylate) (PMMA) was investigated using extreme ultraviolet (XUV) and soft x-ray (SXR) radiation from plasma-based sources. The initial experiment was performed with a 10Hz desktop capillary-discharge XUV laser lasing at 46.9 nm. The XUV laser beam was focused onto the sample by a spherical mirror c...

Cryogenic liquid-jet target for debris-free laser-plasma soft x-ray generation

A new target system based on a continuous cryogenic liquid jet for debris-free laser-plasma soft x-ray generation is described. The system is experimentally evaluated with liquid nitrogen as target material. With this target the photon flux is 4.5310 photons/~sr3pulse! from the l52.88 nm N VI line. Brightness and stability are also investigated for this table-top soft x-ray microscope source. T...

Investigation 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...

PRO O F CO PY [ LX 9056 A ] 095510 PRA Demonstration of high - repetition - rate tabletop soft - x - ray lasers with saturated output

Saturated tabletop lasers operating at 5 Hz repetition rate with average powers 1 W were demonstrated at wavelengths between 16.5 and 13.9 nm in the 4d P1–4p S0 transitions of Ni-like ions. The results were obtained using picosecond laser heating pulses with an energy of only 1 J by optimizing the angle of incidence for maximum energy deposition. Lasing was also observed for shorter wavelength ...
