Laser rock drilling by a super-pulsed CO{sub 2} laser beam.

Description: High power carbon dioxide lasers have successfully been used in drilling or cutting engineering materials such as metals, polymers and ceramics over the years. Can a carbon dioxide laser be used to efficiently drill different rocks in a deep gas well? Research sponsored by US Department of Energy has been carried out to answer this question. This paper will report the study results of using a super-pulsed CO{sub 2} laser beam to drill rocks. A 6 kW CO{sub 2} laser operated at superpulse mode wa… more

Report of near field group

Description: Substantial progress since the Los Alamos Workshop two years ago is reported. A radio-frequency model of a grating accelerator has been tested at Cornell, and extensive calculations compared with observations. Alternative structures consisting of either hemispherical bumps on a plane, or conducting spheres in space, have also been rf modeled. The use of liquid droplets to form such structures has been proposed and a conceptual design studied. Calculations and experiments have examined the effec… more

Application of high powered lasers to drilling and completing deep walls.

Description: High powered laser rock drilling was studied as a revolutionary method for drilling and completing deep gas and oil wells. The objectives of this 2002 to 2003 fiscal year research were to study the concept that large diameter holes can be created by multiple overlapping small beam spots, to determine the ability of lasers to drill rock submerged to some depth in water, to demonstrate the possibilities of lasers for perforating application, and to determine the wavelength effects on rock removal… more
