CO2 laser free-shape cutting of flexible glass substrates
ICALEO 2012: 31st International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2012We investigated CO2 laser free-shape cutting of flexible glass substrates. The technique uses tensile stress to propagate a full-body crack along the perimeter of the glass article to be cut. The tensile stress was generated by the CO2 laser heating and subsequent ambient air cooling process.

Thermochemical modelling in CO2 laser cutting of carbon steel
Journal of Materials Science, 1994A thermochemical heat transfer model in oxygen-assisted laser cutting of carbon steel has been developed in terms of the laser mode pattern, the power density, combustion reaction, kerf width and cutting speed. This model emphasizes the chemical combustion effect as well as the laser mode pattern, which are usually neglected by most existing laser ...

Cutting of aramide fiber-reinforced plastics by Co2 laser
Mechanics of Composite Materials, 1999Comparative characteristics of aramide fiber reinforced plastics (AFRP) made by laser cutting or machining are presented. It is found that the strength of the specimens cut out by laser is 4–25% higher, while the moisture absorption is at least 2 times lower as compared to those cut out by machining. The deviation of the cutting edge size for AFRP 2 mm

Cutting of mullite-alumina ceramic plates with CO2 laser
ICALEO 2004: 23rd International Congress on Laser Materials Processing and Laser Microfabrication, 2004In this work, a comprehensive analysis of the CO2 laser cutting of mullite-alumina ceramic plates is presented. The cut quality was assessed under the criterion of facilitate the comparison of the results obtained using different process parameters and two different assist gas injection systems.

Laser cutting from CO2 laser to disc or fiber laser – Possiblities and challenges
ICALEO 2011: 30th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2011Now, nearly a decade since the introduction of the high brilliance solid state lasers, an evolution of industrial high power laser materials processing is ongoing. In this paper will be focused on the largest market for high power lasers: metal laser cutting. The state-of-the-art of laser cutting with fibre-and disc-lasers

Laser cutting of steel with the revolutionary turbolase T1000 CO2 laser
ICALEO '82: Proceedings of the Materials Processing Symposium, 1982The TURBOLASETM T1000 is perhaps the first laser specifically designed for metal cutting. The T1000 employs Photon’s unique TURBOTUBETM that delivers 1000 watts of solid laser energy to produce smooth, straight cuts with no more than four optical elements in the entire cutting system.

Dual-beam CO2 laser cutting of thick metallic materials
Journal of Materials Science, 1993A dual-beam technique involving two CO2 gas lasers with a power capacity of 1.5 kW each, was used to cut steel and superalloy. A comparison with single-beam CO2 laser cutting showed that dual beams were capable of enhancing the cutting thickness and speed without deteriorating the quality of cut. Heat-conduction models, assuming the laser beams as line
