A high-power KrF system has been used to heat solid targets with laser energies of up to 1 J in 3 ps. Single-shot irradiances of up to 1017 W-cm-2 were achieved at the target surface. A number of diagnostics were used to investigate the plasmas produced. When an ASE background containing about 20% of the short-pulse energy in a 10-ns interval was present, the X-ray spectra indicated an electron temperature of about 400 eV and a density of a few times 1022 cm-2. When the prepulse level was kept below 10-3 of the main pulse, measurements indicated plasmas with temperatures of 400 eV at close to solid density. The production of hot electrons was investigated using titanium targets overcoated with CH, and observing the Ti Kα emission. These measurements also confirmed the low prepulse level, since Kα emission was weak when only 0.5 μm of plastic overcoat was used. The experimental results were simulated with a 1-D hydrocode.

A programme of research by UK Universities and overseas collaborators at the SERC Central Laser Facility is directed to the development of XUV lasers based on recombining laser produced plasmas. Laser amplification has been demonstrated for recombination to hydrogenic ions C VI and F IX with Hα laser amplification at 182 and 81 Å respectively, and for lithium like ions, namely Aℓ, XI with 4f-3d and 5f-3d laser amplification at 150/154 and 106/104 Å respectively and Cℓ XV 4f-3d at 83 Å. An initial study of Na-like Cu XIX has been made. Current work is looking for ways to improve the efficiency, increase the gain length and reduce the wavelength to reach the 44 Å edge of the water window. The review summarises past work and outlines current work. © 1988 SPIE.

Kiehn GP, Garvey T, Smith RA, Willi O, Damerell AR, West Jet al., 1988, Absolute calibration of an xuv time resolving spectrograph, Proceedings of SPIE - The International Society for Optical Engineering, Vol: 831, Pages: 150-153, ISSN: 0277-786X

A time resolving XUV spectrograph has been developed for x-ray laser research. A grazing incidence flat field grating is coupled to a soft x-ray streak camera to provide high temporal resolution over a large spectral range. Wavelengths between 50 Å and 400 A are focused onto a flat field, allowing detectors to be easily coupled to the spectrograph. Time resolved spectra covering any ''100 A window within flat field can be recorded using a streak camera. The spectrograph and detector were absolutely calibrated in the XUV spectral region using synchrotron radiation. The instrument and its characterization will be described. The wavelength range of the spectrograph has been extended to approximately 11 R through the use of a higher periodicity flat field grating. Preliminary spectroscopic results will be presented. © 1988 SPIE.

Recent x-ray laser research carried out at the Rutherford laboratory has concentrated on examining recombination pumping in H-like and He-like ions. Laser irradiation of thin fiber targets establishes a rapidly expanding plasma column in which population inversions are created during the recombination cascade. Experimental results in H-like carbon and fluorine systems will be presented along with the preliminary analysis of Li-like Al and Cl systems. © 1988 SPIE.
