“…At high intensities the signal is proportional to the square root of the intensity (slope 1/2 in Fig.5), as already pointed out. Such an intensity dependence might be due to the saturation of an inhomogeneously broadened line or, like in the present case, group of lines, if the inhomogeneous width is larger than the unsaturated homogeneous linewidth [14].…”

The far-infrared magneto-photoconductivity due to optical transitions from the acceptor ground state into quasi-bound Coulomb states in p-Ge has been investigated at low temperatures as a function of intensity applying a high-power cw molecular laser. For intensities above about 1 mW/cm 2 the photoconductive signal shows a square root dependence on intensity, which is attributed to nonlinear free carrier capture in the low compensated material. The experimental results are analyzed in terms of a rate equation model yielding the kinetic parameters of the carrier generation-and recombination process involved.

“…Additionally, nonlinear absorption mechanisms may substantially modulate the photons' temporal distribution. For example, apart from the non-linearities associated with high fields, those that collectively saturate, or "use up" available electronic transitions can subject the downstream part of the pulse to stronger absorptivities than its upstream end [46]. Finally, if the interval ∆τ LCLS becomes too short, the overall model for propagation will acquire additional complexity due to the fact that the medium's state will bear the imprint of preceding pulses.…”

The concept and the feasibility of an x-ray FEL is based on the theoretical and experimental work of many people. We are indebted to those scientists and engineers who prepared the ground for this Design Study. A special thanks is due to the LCLS Study Group, led by Herman Winick, that conducted the first exploratory and design studies of an x-ray FEL based on the SLAC linac following the 1992 SLAC Workshop on Fourth-Generation Sources, where the concept was introduced by Claudio Pellegrini.The Design Study has benefited greatly from comments and suggestions made during reviews. We are grateful to the members of the LCLS Design Review Committee whose members were: Joe Bisognano (Chairman), Ilan Ben-Zvi, Alex Chao, Bill Colson, Gary Deis, Efim Gluskin, Hank Hsieh, Gerd Materlik, Joachim Pflueger, Marc Ross, and Ross Schlueter. Previous reviews included an early LCLS review chaired by Ilan Ben-Zvi and an undulator review chaired by Efim Gluskin. Their comments and suggestions proved to be very useful, and some of them are incorporated in the Design.We thank Terry Anderson (cover design), Frank Cebulski (technical editing), Ruth McDunn (production), Berah McSwain (project administration), and Thelma Walker (administration) for their valuable contribution to this report. 3UHIDFHThe Stanford Linear Accelerator Center (SLAC), in collaboration with Los Alamos National Laboratory, Lawrence Livermore National Laboratory, and the University of California at Los Angeles, is proposing to build a Free-Electron-Laser (FEL) R&D facility operating in the self-amplified spontaneous emission (SASE) mode in the wavelength range 1.5-15 Å. This FEL, called "Linac Coherent Light Source" (LCLS), utilizes the SLAC linac and produces sub-picosecond pulses of short wavelength x-rays with very high peak brightness and full transverse coherence.Until about the 1960s x-rays were obtained from Roentgen tubes. After the first observation of synchrotron radiation [1] and the evolution of cyclic electron synchrotrons and then storage rings for high energy physics applications, it was realized that these accelerators could be exploited as much more intense x-ray sources. Storage ring synchrotron light sources have now evolved through three generations. The first-generation sources utilized radiation from storage rings built for high-energy physics purposes. These included Tantalus at the University of Wisconsin, ACO and DCI at LURE, SPEAR and PEP at SLAC, DORIS and PETRA at DESY, Adone at Frascati, VEPP-2M and VEPP-3 in Novosibirsk, and CESR at Cornell. Initially only bending magnet radiation was used and experiments were carried out parasitically during high-energy physics runs. The second-generation machines were purpose built, but still initially used bending magnet radiation. The first round of second-generation sources included the SOR-ring in Tokyo, the SRS at Daresbury, Aladdin in Wisconsin, the Photon Factory at KEK, and the NSLS at Brookhaven. Eventually, insertion devices were added to these facilities, but only in limited number becau...

“…Transient phenomena in laser-matter interactions involving powerful and ultra-short pulse laser sources may only be modelled using a semi-classical approach in the time domain [1][2][3]. In this context the electromagnetic wave is described by Maxwell equations and is coupled to the Bloch model for matter via an expression for the polarization.…”

In this article we derive new time discretizations for the numerical simulation of Maxwell-Bloch equations. These discretizations decouple the equations, thus leading to improved efficiency. This approach may be combined with the fulfilment of physical properties, such as positiveness properties, which are not accounted for by classical schemes. Our time discretizations are moreover proved to be nonlinearly stable.
