The DIAMOND™ E-1000 from Coherent (Santa Clara, CA) is a sealed 1 kW CO2 laser that measures less than 1497mm × 471mm × 384mm, including its integrated power supply. It is suitable for use in small machines or space-sensitive applications involving cutting, perforating, and drilling of paper, plastic films, plastics, glass, carbon composites, and thin metals. The laser requires no external gas supply and is easy to mount on a moving robot arm.
It reaches cutting speeds equivalent to traditional 2 kW CO2 lasers, and achieves spatial mode quality (M2<1.2) and a square wave pulse shape that delivers up to 2.5 kW of peak power. It cuts mild steel sheets up to 6 mm thick, and stainless steel sheets up to 3mm thick.
