چکیده
High power carbon dioxide lasers have successfully been used in drilling or cutting ngineering materials such as metals, polymers and ceramics over the years. Can a arbon dioxide laser be used to efficiently drill different rocks in a deep gas well? esearch sponsored by US Department of Energy has been carried out to answer this uestion. This paper will report the study results of using a super-pulsed CO2 laser beam drill rocks. A 6 kW CO2 laser operated at superpulse mode was used to carry out the sts. Both linear tracks and deep holes were produced on the rocks. The energy required remove a unit volume of rock, specific energy, was determined. Test results show that perpulsed CO2 laser beam can be efficiently used to drill deep, large diameter holes in etroleum rocks with the assistance of purging gas.

The effect of surface roughness on 1050 aluminum alloy weld profile welded by pulsed Nd:YAG laser
Surface roughness in the welding processes is one of the important parameters in the laser welded metal connections which affects laser beam absorption directly. When the laser beam is irradiated to the surface of the base metal, the surface roughness plays an important role in the amount of beam absorption and the amount of melting achieved and directly affects the penetration depth. The main ...

In this paper, we present a high accuracy laser range finder and velocimeter using ultra-fast time-to-digital converter (TDC). The system operation is based on the measuring the round-trip time of a narrow laser pulse. A low-dark current high-speed PIN photodiode is used to detect the triggered laser beam and to produce start signal. The pulsed laser diode generates 45W optical power at 30ns du...
