An x-ray laser shadowgraphy experiment was conducted on Xingguang-II laser facility in 1996. A multi-layer spherical mirror was used as an imaging element and a high sensitivity CCD camera as a detector. We measured the near-field image of the Ti x-ray laser beam. With a Ti x-ray laser beam as a backlight source, we obtained a clear Cu mesh image, demonstrating the potential as advanced diagnostic measurements to study high density plasmas in inertial confinement fusion research.

A comparison has been made of performance of the neon-like chromium soft x-ray lasing at 28.5 nm driven by a double 900 ps pulse at 6 TW/cm2, with that driven by a double 200 ps pulse at similar irradiance. The double 200 ps pulse has been found to be much more efficient to drive x-ray lasing with higher intensity.

The effects of atomic number Z on the energy distribution of hot electrons generated by the interaction of 60fs, 130mJ, 800nm, and 7×1017W/cm2 laser pulses with metallic targets have been studied experimentally. The results show that the number and the effective temperature of hot electrons increase with the atomic number Z of metallic targets, and the temperature of hot electrons are in the range of 190–230keV, which is consistent with a scaling law of hot electrons temperature.

New method of adjusting and aligning a grazing incidence grating spectrometer

He Shao-Tang; Chen Yuan; Chunyu Shutai; Peng Han-sheng

A compact grazing incidence grating spectrometer with spectral range of 2–32 nm resolution of 0.0005 nm, and about 3.6‐kg weight has been manufactured, which can meet the requirements of current x‐ray laser experimental research. During the construction, as a new method, we used a 3D measuring machine to finish the adjustment of spectral elements and invented a new method of alignment with a fiducial plane when using the spectrometer in an experiment.

Chunyu Shutai; He Shao-Tang; Zhang Qi-Ren; He An; Shen Huazhong; Ni Yuan-Long

The experimental investigations of double-pass amplification of X-ray laser in neon-like germanium were carried out by use of Shengguang laser facilities.In these experiments a molybdenum/silicon multilayer mirror Was used at normal incidence, a flat-field grating spectrograph was used to measure the intensity of lasing lines. We observed the doublepass emission intensity in the neon-like germanium at 23.2 and 23.6 nm that was 5 times larger than that of the single-pass ASE. The enhartcement of double-pass emission could be much larger if the operation period of multilayer mirror was counted in. The damage of multilayer mirror irradiated by laser plasma was measured simultaneously, the lifetime of Mo/Si multilayer mirror was about 440—700ps.In addition, we measured the beam divergence of lasing beam,the resnlts showed that the beam divergence in the vertical direction was about 22 mrad and in the horizontal direction about 12 mrad.
