Raman pulse compression of excimer lasers for application to laser fusion
, 1979Application of efficient ultraviolet excimer lasers such as the 248 nm KrF laser to laser fusion requires that long laser pulses be efficiently converted to short pulses at high intensity. The backward Raman amplifier is shown to be a promising candidate

The ablation characteristics of a 266 nm Nd:YAG laser and a 193 nm excimer laser were compared by successive experiments by inductively coupled plasma mass spectrometry (ICP-MS), using the same ablation cell without changing the carrier-gas flows within ...

Excimer lasers and laser systems
Applied Physics A: Materials Science & Processing, 1999The results of the experimental study of UV lasers and laser systems pumped by different methods are presented. Two lasers were pumped by electron beams from Marx generators. Three lasers were pumped by transverse discharge with UV preionization.

Two‐photon processes in defect formation by excimer lasers in synthetic silica glass
, 1988Defect formation in dehydrated silica glasses was investigated using various excimer lasers with different energies. The ArF laser (6.4 eV) generates the E’ center more effectively than the KrF laser (5.0 eV), while the XeCl laser (4.0 eV) generated no ...

Excimer Laser Intrastromal Keratomileusis
American Journal of Ophthalmology, 1992We studied 30 eyes in 22 patients with severe myopia who underwent myopic keratomileusis combined with excimer laser refractive correction. The goals of the study were to evaluate the efficacy of the procedure in decreasing myopia, to assess the response of the cornea to intrastromal photoablation, and to examine the relationship between the number of ...

Excimer ions as possible candidates for VUV and XUV lasers
, 1985Optical transitions in ionic excimer molecules seem to be suitable candidates for lasers in the VUV and XUV region. Potential curves, transition wavelengths, radiative lifetimes, and cross sections for stimulated emission are calculated for several ...

Excimer laser photorefractive keratectomy
American Journal of Ophthalmology, 1995Excimer laser photorefractive keratectomy has been used for the correction of myopia, hyperopia and astigmatism. This laser removes tissue through a process termed photoablative decomposition, in which incident photon energy is sufficient to break molecular bonds.

Injection-locking unstable resonator excimer lasers
, 1983We review the basic criteria for effective and efficient injection locking of high-power excimer lasers, and enumerate the various parameters of practical concern for experimental implementation. Various injection schemes are compared and the fundamental

Radiative and kinetic mechanisms in bound-free excimer lasers
, 1977An interactive kinetic model for bound-free excimer lasers is described, with particular emphasis on the electron beam pumped rare gas systems. Important kinetic processes and the interaction of the photon field with excited states are examined in detail.
