The first demonstration of laser action in ruby was made in 1960 by TH Maiman of Hughes
Research Laboratories, USA. Many laboratories worldwide began the search for lasers …

A theoretical model of soft x-ray lasers in hot laser-produced plasmas using a Maxwell-Bloch
formalism has been developed and implemented in a numerical code (COLAX). First …

Saturated operation of a laser at a wavelength shorter than 6 nm is demonstrated. The
output of the Ni-like Dy laser at 5.86 and 6.37 nm, pumped by the VULCAN 1.05-μm Nd …

In this paper we review the development of a soft-x-ray laser at 21.2 nm, recently carried out
at the Laboratoire de Spectroscopie Atomique et Ionique. Amplification is generated by …

X-ray free-electron lasers, delivering up to 1× 1013 coherent photons in femtosecond pulses
are bringing about a revolution in X-ray science,,. However, some plasma-based soft X-ray …

Traveling-wave irradiation with a laser pulse of duration∼ 1 picosecond has been shown to
achieve saturated operation of Ne-and Ni-like x-ray lasers. Gain at 196 Å was confirmed by …

A variant of a grazing-incidence pumping (GRIP) scheme for Ni-like x-ray lasers using a
single shaped pulse from a 10-Hz Ti: sapphire laser system has been demonstrated …

X-ray lasers have been the subject of intense research since the mid-1980s owing to
continuous advances in technology and computer engineering. By the mid-1990s, extreme …

The interaction between radiation and matter in an x-ray laser occurring in a cylindrical laser-
produced plasma is investigated by means of the Maxwell-Bloch equations with level …

The transient-excitation pumping scheme, in which a picosecond duration pulse rapidly
heats the plasma preformed by a low-intensity nanosecond pulse, was used to pump the Ne …
