High Speed Pulse Technology, Volume IV: Sparks and Laser Pulses covers the production and practical aspects of sparks and laser pulses for the generation and utilization of high speed pulsed of energy in different forms. This volume consists of seven chapters and begins with reviews of the classification of photographic methods of high-speed analysis, specifically the motion analysis of rapid events by white light pulses. The next chapters examine the sources of white pulse light and nanosecond radiation. The remaining chapters discuss the applications of the technology in photography, photolysis, laser pumping, and visualization of flows, cracks, and particles. This book will prove useful to physicists, electrical and other engineering fields, teachers, and students who are interested in sparks and laser pulses.
Three devices, a short-pulse laser, a coaxial Pockel cell shutter, and a single-crystal transmission-line Pockel cell, have been evaluated as techniques for producing laser pulses approximately 1 nsec in duration. The short-pulse laser has produced pulses that range from 0.5 nsec to 2.0 nsec in duration with peak powers from 25 to 300 kW. Pulses 1.8 nsec in duration FWHM (full width at half maximum) with risetime of less than 0.4 nsec have been gated from Q-switched ruby laser pulses by the coaxial shutter, while pulses 1.3 nsec FWHM have been obtained in the same fashion with a transmission-line shutter.

High Speed Pulse Technology: Volume II: Optical Pulses - Lasers - Measuring Techniques focuses on the theoretical and engineering problems that result from the capacitor discharge technique. This book is organized into three main topics: light flash production from a capacitive energy storage; signal transmission and ranging systems by capacitor discharges and lasers; and impulse measuring technique. This text specifically discusses the air spark under atmospheric conditions, industrial equipment for laser flashing, and claims for light transmitting system. The application of light impulse signal transmission, impulse measurements by means of spark gaps, and conversion factors of various energy units are also described. This publication is recommended for eager electrical engineering and physics students interested in optical pulses, lasers, and measuring techniques.
Bringing together scattered literature from a range of sources, Laser Spectroscopy and ItsApplications clearly elucidates the tools and concepts of this dynamic area, and providesextensive bibliographies for further study.Distinguished experts in their respective fields discuss resonance photoionization, laser absorption,laser-induced breakdown, photodissociation, Raman scattering, remote sensing,and laser-induced fluorescence. The book also incorporates an overview of the semiclassicaltheory of atomic and molecular spectra.Combining background at an intermediate level with an in-depth discussion of specifictechniques, Laser Spectroscopy and Its Applications is essential reading for laser and opticalscientists and engineers; analytical chemists; health physicists; researchers in optical,chemical, pharmaceutical, and metallurgical industries. It will also prove useful for upperlevelundergraduate and graduate students of laser spectroscopy and its applications, andin-house seminars and short courses offered by firms and professional societies.
Measurements have been taken of the radiative flux density, the spectrum, and the temporal behavior of laser induced underwater sparks. When a 30-MW Q-switched ruby laser was focused water, the resulting spark revealed a blackbody-like spectrum with a temperature of 15,000K. The spark was delayed in time by 15 nsec with respect to the laser pulse and had a temporal behavior very similar to the laser pulse producing it. (Author).
The production of a spark in atmospheric air by means of a mode-locked laser beam was investigated and some observations on the breakdown threshold conditions and subsequent development of the spark are reported. (Author).
