Starting from intense short-pulse KrF (248 nm, 25 mJ, 400 fs), ArF (193 nm, 10 mJ, sim1 ps), and Ti:sapphire (810 nm, 100 mJ, 150 fs) laser systems, schemes for the generation of fixed-frequency and tunable VUV and XUV radiation by nonlinear optical

Optimal schemes for the creation of a transient population inversion between the ground and excited states of an ion in a subpicosecond-pulse laser-produced plasma are discussed. First results on experimental investigations of possible amplification

High-order frequency mixing experiments using the radiation of a high-power Ti:sapphire laser and its second harmonic are described and discussed. Linearly and circularly polarized light fields with comparable intensities have been used. For the theo

By in innershell photoionization of rubidium vapor with soft X-rays from laser-produced plasmas the metastable 4p 5 5s levels in the rubidium ion are populated. Starting from these levels, five Raman-type lasers on the 4p 5 5p-4p 5 4d transitions in

We report on what is to our knowledge the first subpicosecond-pulse amplification experiments in an F2 gain module at 157 nm. 500-fs seed pulses were produced by a four-wave mixing process in xenon by excitation with KrF short-pulse radiation. The am

Subpicosecond pulses at 193 nm, generated by a nonresonant difference-frequency mixing process in xenon, have been amplified in an ArF excimer gain module to output energies of as much as 10 mJ. Investigations on the gain characteristics of the ArF e

By excitation of cadmium vapor with a high-peak-power KrF excimer laser pulse, fluorescence of an atomic transition at lambda = 508 nm is induced by a two-photon ionization process followed by fast recombination. The nonlinear response of the medium

Currently, there exists considerable interest in the generation of coherent radiation in the xuv spectral range. Due to the development of compact short-pulse highpeak power laser systems, high-order harmonic generation has become a useful laboratory

Three different experimental approaches for the generation of coherent VUV and XUV radiation are studied and discussed. With a 400 fs KrF excimer laser system tunable VUV radiation around 155 nm with a peak power of approximately 0.5 GW has been gene

The generation of high-order harmonics of intense short-pulse laser radiation has been intensively studied during the last years [1]. It is of great importance to learn how to manipulate the high-order harmonic signals. The solution of this problem c
