Looking to higher power for laser speed?

December 13, 2005


Laser beam sources with higher output powers and improved beam qualities have expanded the range of laser applications. Most system's lasers have power higher than 2 kW. Higher power does not always increase the speed, however. Increasing the power during thermal cutting value may cause increased heat-affected zones on the material and place higher demands on the motion system, thus limiting the cutting speed. A new patented cutting machine, the diffusion-cooled CO2 slab laser, may offer improved beam quality and smaller focus diameters under conditions comparable to conventional fast-axial-flow CO2 laser with 4-kW output power.
