250W CO2 Laser


The new DIAMOND E-250 is the latest member of the E‑Series CO2 laser family from industry leading Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR).  The power range for the Coherent E-Series product line extends from 150W to 1000W, with thousands of lasers installed worldwide.  The new DIAMOND E-250 is a fully sealed, pulsed CO2 laser offering 250W of average power and > 750W of peak pulse power.  

The DIAMOND E‑250 has its RF power module integrated within the same housing as the laser tube, eliminating the RF umbilical cable required in older Coherent K-series lasers as well as other suppliers with separate RF power supply units.  The integrated DIAMOND E-250 design utilizes state-of-the-art electronics, and is more compact and reliable than any other comparable CO2 laser on the market today. With an output wavelength of 10.6 µm, the DIAMOND E-250 targets a wide range of materials processing applications in which throughput, quality, process capability and low cost of ownership are critical, and where a minimal footprint is desired.  

Applications include converting, cutting, drilling, scribing, engraving, and marking of a wide variety of materials such as paper, cardboard, acrylic, plastic, glass, ceramics, textiles, denim, leather, rubber, thin metals, wood and stone. In addition to the DIAMOND E-250, Coherent is also offering the new DIAMOND E-250i in the same advanced compact configuration with an output wavelength of 9.4 µm.  The shorter wavelength is ideal for processing a number of materials such as films and plastics used in mobile devices.
