A technical and commercial comparison of fiber laser and CO2 laser cutting
ICALEO 2012: 31st International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2012This paper presents a direct comparison of Fiber laser and CO2 laser cutting machines from a ‘what laser should you buy next?’ point of view. Both types of machine have their drawbacks and advantages, and a direct comparison needs to compare costs, cutting speeds, cut quality and several other factors including maintenance and safety considerations ...

An investigation of quality in CO2 laser cutting of aluminum
CIRP Journal of Manufacturing Science and Technology, 2009Abstract Aluminum alloys are widely used in the aeronautics industry and nowadays have become of importance to the automotive industry as well. This paper investigates experimentally the quality of laser cutting for the aluminum alloy AA5083, with the use of a pulsed CO2 1.8 kW laser cutting system.

Slate is a natural stone which has the characteristic that shows a well-developed defoliation plane, allowing to easily split it in plates parallel to that plane which are particularly used as tiles for roof building. At present, the manufacturing of slate is mostly manual, being noisy, powdery and unsafe for the worker.

State of the art in laser cutting with CO2 lasers
ICALEO '90: Proceedings of the Laser Materials Processing Conference, 1990The paper gives a short overview of the R+D activities concerning cutting with CO2 lasers in the Federal Republic of Germany. This includes some results of a joint research project, in which 16 institutes and companies worked together during the last three years as well as some new industrial applications and their physical problems.

CO2 laser cutting of stained glass
The International Journal of Advanced Manufacturing Technology, 1996This paper covers the CO2 laser cutting of stained glass using a Ferranti MF400 CNC laser cutting machine. The report examines the various laser cutting parameters required to generate a cut surface in glass which will require minimal post-treatment to be carried out, and also investigates the degree of geometrical intricacy that can be attempted ...

Cutting and welding using a CO2 laser
Optics & Laser Technology, 1972Abstract Of all the types of lasers now available, the CO 2 laser is particularly suitable for materials working. It has a very high efficiency (15–20%) and a high out-put power (up to several kW). When the laser light is focused by means of a lens or a mirror, a c.w. power density of more than 10 9 W cm -2 can be attained.

CO2 laser cutting of natural granite
Optics & Laser Technology, 2016Abstract Commercial black granite boards (trade name: “Zimbabwe black granite”) 10 mm thick, were successfully cut by a 3.5 kW CO2 laser source. Cutting quality, in terms of kerf width and roughness of the cut wall, was assessed by means of statistically planned experiments.

New aspects of cutting with CO2-lasers
ICALEO '91: Proceedings of the Laser Materials Processing Symposium, 1991Experimental investigations reveal that higher cutting velocities can be obtained by using circularly polarized laser light instead of using laser light linearly polarized parallel to the cutting direction. This is an unexpected effect because of the better absorption of the parallel polarization at the workpiece in cutting direction.
