Abstract:

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 Joulesliter-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.
