"Basics of laser physics provides an introductory presentation of the field of all types of lasers. It contains a general description of the laser, a theoretical treatment and a characterization of its operation as it deals with gas, solid state, free-electron and semiconductor lasers and, furthermore, with a few laser related topics. The different subjects are connected to each other by the central principle of the laser, namely, that it is a self-oscillating system. Special emphasis is put on a uniform treatment of gas and solid-state lasers, on the one hand, and semiconductor lasers, on the other hand. "

"This book offers the reader a practical guide to the control and characterization of laser diode beams. Following a short introduction to the working principles of laser diodes, the book describes the basics of laser diode beams and beam propagation, including Zemax modeling of a Gaussian beam propagating through a lens. The core of the book is concerned with laser diode beam manipulations, collimating and focusing, circularization and astigmatism correction, coupling into a single mode optical fiber, diffractive optics and beam shaping, and manipulation of multi transverse mode beams. The final chapter of the book covers beam characterization methods, describing the measurement of spatial and spectral properties, including wavelength and linewidth measurement techniques. "

"The PUILS series delivers up-to-date reviews of progress in Ultrafast Intense Laser Science, a newly emerging interdisciplinary research field spanning atomic and molecular physics, molecular science and optical science which has been stimulated by the recent developments in ultrafast laser technologies. Each volume compiles peer-reviewed articles authored by researchers at the forefront of each their own subfields of UILS. These are followed by reports of cutting-edge discoveries. This eighth volume covers a broad range of topics from this interdisciplinary research field, focusing on molecules interacting with ultrashort and intense laser fields, advanced technologies for the characterization of ultrashort laser pulses and their applications, laser plasma formation and laser acceleration."

"ABSTRAKThe current design practice for concrete bridge decks requires a top mat and a bottom mat of reinforcing bars. The chloride attack of the top mat reinforcing bars is a major cause of deterioration of bridge decks. Emprical evidence has indicated that the top transverse reinforcing bars can essentially be eliminated without jeopardizing the structural integrity of a deck. To explore this issue, the behavior of a four-span highway bridge deck subjected to a test truck and normal traffic loads is being investigated. The behavior of the bridge under the test truck and various combinations of truck loads has been analyzed with the finite-element method. These result confirm the fact that a properly designed bridge deck does not requiere top transverse reinforcement for sustaining the negative bending moment induced by traffic loads. "
