Book Description
A new pulsed laser discharge concept is proposed to meet military and civilian requirements for efficient operation of compact, high energy CO2 lasers. This discharge concept promises pulse lengths of up to 100 microseconds duration scalability to multi-kilojoule pulsed energy, high volumetric efficiency (> or = 50 Joules/liter-atm) and high electrical efficiency (> or = 20%). This discharge concept relies on a new method for maintaining discharge stability for long pulse durations. This new CO2 laser discharge concept promises increased efficiency, repetition rate, laser pulse length, extracted energy per unit volume and reliability. The concept utilizes a current source to insure volumetric stability. Such a source will not stabilize the discharge against streamer formation. Streamer formation can be inductively inhibited by the use of RF. Hence an RF current source could result in a more stable laser discharge.

Book Description
This report describes an electric-discharge carbon dioxide mixing laser which has been designed and constructed at MRL. The laser, which utilizes a plasma injection stabilized discharge in atmospheric-pressure nitrogen, delivers an output power of 50 kW for reservoir-limited durations of 3 seconds at an overall efficiency of 7%. Additional keywords: schematic diagrams; charts; continuous wave lasers; high power; ionization; high pressure; resonators; gases; electric power; vacuum pumps; control panels; Australia. (Author).

Book Description
In the thirty years since the invention of the CO2 gas laser, the major design issue has shifted from how to obtain the desired power level to how to achieve reliable operation. At the same time, the opening of many laser development facilities in the Former Soviet Union has allowed their achievements and design approaches to be understood and appreciated for the first time. Further, the industrial laser user community has identified a number of emerging applications at higher power levels (15-20 kW) than are attainable by most commercial devices. In High Power Lasers - Science and Engineering, the designers, developers and users of high-power gas laser systems discuss design approaches, methods of enhancing performance, new applications, and user requirements.

Book Description
Introduction to Gas Lasers: Population Inversion Mechanisms focuses on important processes in gas discharge lasers and basic atomic collision processes that operate in a gas laser. Organized into six chapters, this book first discusses the historical development and basic principles of gas lasers. Subsequent chapters describe the selective excitation processes in gas discharges and the specific neutral, ionized and molecular laser systems. This book will be a valuable reference on the behavior of gas-discharge lasers to anyone already in the field.

Book Description
Optical science, engineering, and technology have grown rapidly in the last decade so that today optical engineering has emerged as an important discipline in its own right. This series is devoted to discussing topics in optical engineering at a level that will be useful to those working in the field or attempting to design systems that are based on optical techniques or that have significant optical subsystems.
