Book Investigation and Operation of a Carbon Dioxide TEA Laser

Download or read book Investigation and Operation of a Carbon Dioxide TEA Laser written by William Frederick Bassett and published by . This book was released on 1973 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasing has been achieved at 10.6 microns using a double discharge CO2 TEA configuration. The double discharge configuration uses three electrodes. The third, 'trigger, ' electrode in this particular device consists of glass encapsulated nichrome wires. The third electrode is responsible for corona formation--the dominant preionization mechanism. A parametric analysis of the discharge was conducted. The discharge was found to be dependent on the gas mixture, the gas flow rate, the voltage rise time and the voltage pulse shape. It was found that satisfactory discharge operation leading to lasing was limited to a very small region of parameter space having a helium percentage of not less than 90% (with 5% CO2 and 5% N2), and a rise time on the order of 3 microsec. Lasing action yielded 5 joules/pulse. The energy was limited by the optical components used, and it is felt that the energy can be increased to approximately 18 joules/pulse using different circuit parameters in conjunction with improved optical components.

Book Investigation of Material Damage  Pressure Pulses Produced by Carbon Dioxide Laser Radiation

Download or read book Investigation of Material Damage Pressure Pulses Produced by Carbon Dioxide Laser Radiation written by John F. Ready and published by . This book was released on 1976 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes work performed in a continuing program of investigations on the mechanisms by which high power pulsed CO2 laser radiation interacts with target surfaces. The experimental work has been performed using a pulsed CO2 TEA laser capable of delivering up to 10 to the 9th power/sq cm to the target surface in a pulse of duration around 100 nanoseconds.

Book A Multiple Pulse CO2 TEA Laser for Use in Thermal Blooming Studies

Download or read book A Multiple Pulse CO2 TEA Laser for Use in Thermal Blooming Studies written by T. D. J. Cameron and published by . This book was released on 1980 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design, performance and operating characteristics of a multiple pulse CO2 TEA laser constructed at AWRE for use in thermal blooming studies is described. Using unstable resonator optics, at the maximum pulse repetition frequency of approx. 10.4 Hz, this laser yielded a good quality output beam of mean power 28 + or - 2 W. (Author).
