A comparative study on fusion cutting with disk and CO2 lasers
ICALEO 2010: 29th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2010In recent years, several studies on laser beam fusion cutting demonstrated significant differences in the characteristics of the well-established CO2 laser cutting and cutting with solid-state disk and fiber lasers. The reasons for the observed differences in cutting efficiency and cut edge quality are still the subject of the current research and not ...

Energy conditions of a high-quality cut at the laser-oxygen cutting with fiber and CO2 lasers
ICALEO 2013: 32nd International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2013The fiber laser is a promising beam source for metal cutting. The modern level of research and practical application, however, enables to conclude that the fiber laser does not always present an effective alternative to the CO2 laser. Comparative investigations of the fiber and CO2 lasers are topical.

Cutting weeds with a CO2 laser
Weed Research, 2001Stems of Chenopodium album. and Sinapis arvensis. and leaves of Lolium perenne. were cut with a CO2 laser or with a pair of scissors. Treatments were carried out on greenhouse‐grown pot plants at three different growth stages and at two heights. Plant dry matter was measured 2 to 5 weeks after treatment.

The effects of power rippling on CO2 laser cutting
Optics & Laser Technology, 1997Abstract A power rippling method was proposed in this study to improve the cut edge quality by disturbing the natural frequency of the periodic striations in high power C02 laser cutting. A pilot study was also designed and set up to examine the power responsibility of the laser system, which is externally controlled by a modulated analogue signal ...

CO2 laser cut quality of 4130 steel
International Journal of Machine Tools and Manufacture, 2003Samples of 4130 steel were cut on a CO2 laser cutting system and the combined effects of power and feed rate on kerf width, surface roughness, striation frequency and the size of heat affected zone (HAZ) have been studied. Regression analysis was used to develop models that describe the effect of the independent process parameters on laser cut quality.

CO2 laser cutting of flexible glass substrates
ICALEO 2011: 30th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2011We investigated CO2 laser cutting of flexible glass substrates using water cooling jets. We found thelaser beam length and width only slightly affected the laser cutting speed. We attribute the weak dependence to the rapid thermal homogenizing process in flexible glass. This paper discusses the optimallaser cutting process window.

Effects of plasma on CO2 laser cutting quality
Optics and Lasers in Engineering, 1988Abstract In CO 2 laser cutting, the measurement of plasma size and transmittance is necessary since the plasma appearing on the surface of the workpiece absorbs a fraction of the incident energy and acts as a heat source, enhancing the cutting process.

Experimental investigation into CO2 laser cutting parameters
Journal of Materials Processing Technology, 1996Abstract The quality of laser cuts is of the utmost importance in laser processing. As laser systems are becoming more demanding, the need for developments in the area of monitoring, diagnosis, regulation and modeling becomes essential to achieve and maintain a high-quality cutting process.
