Laser Drilling of Natural Stones
Materials Science Forum, 2006Following previous work focused on the laser processing of natural stones, we present in this paper the results of the study carried out to verify the feasibility of the lasers to drill slate tiles and granite slabs. The two types of laser equipments most used in the industry (CO2 and Nd:YAG) have been used to fulfil a comparative study.

Investigation into drilling speed during laser drilling of metals
Optics & Laser Technology, 1988Abstract In the present study, four materials, nickel, tantalum, EN58B and titanium are examined, and information about the drilling speed is obtained. A statistical analysis of the results for drilling speed is undertaken, and the significance of each factor examined is determined.

Acoustic phenomena during laser drilling
ICALEO 2007: 26th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2007Precision laser drilled holes are used to film cool many jet engine components. State-of-the-art military engines involve over 1.2 million cooling holes, most of which are laser drilled. Current film cooling air flow variations are greater than desired due to: (1) casting variations, (2) coating thickness variations, and (3) laser drilled hole location,

Basic Concepts of Laser Drilling
2009The state of the technology of Open image in new window s pulse laser applications is dominated by single pulse drilling, percussion drilling and even trepanning used for high speed drilling with melt expulsion. However, short ps pulses have to be addressed anyway, since there are technical aspects in addition to achieve high speeds in drilling, namely,

Laser Cutting, Drilling and Piercing
2010The idea of cutting with light has appealed to many from the first time they burnt paper on a sunny day with the help of a magnifying glass. Cutting centimetre-thick steel (Figure 3.1) with a laser beam is even more fascinating!

ICALEO '95: Proceedings of the Laser Materials Processing Conference, 1995
The drilling of very large numbers of small holes in the leading edges of wing skins can permit the control of the laminar flow there by means of suction through the wing skin. There have been wing “gloves” with arrays of laser-drilled holes prepared by Boeing for subsonic and supersonic test aircraft for NASA tests.
