CO2 LASERS FOR MATERIALS PROCESSING
May 2000Coherent Inc.Request Info
Coherent Inc.'s Laser Group has released the Diamond Gi and Ki series CO2 lasers for cutting, converting, drilling, engraving, marking and welding. They were designed to process materials that have a higher absorption rate at 9.4 µm than at the standard 10.6-µm output, such as polyimide. The compact, sealed lasers also have the company's proprietary Brilliance integrated features for sharp spot size and high energy densities. The 100-W G-100i has a pulse rise-and-fall time of <80 µs and a peak power of 250 W. The K-125i and K-225i have pulse rise-and-fall times of <40 µs, with the latter 225-W model delivering a peak power of 650 W. The fast optical rise time and high peak power allow fast cutting and produce a small heat-affected zone. All three lasers feature an M2 of <1.3.
