The new DIAMOND E-250 is the latest member of the E-Series CO₂ laser family from Coherent Inc. The power range for the Coherent E-Series product line extends from 150W to 1000W, with thousands of lasers installed worldwide. The DIAMOND E-250 is a fully sealed, pulsed CO₂ laser offering 250W of average power and more than 750W of peak pulse power The 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 design utilizes state-of-the-art electronics.

With an output wavelength of 10.6µm, the DIAMOND E-250 targets a 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 9.4µm. The shorter wavelength is ideal for processing a number of materials such as films and plastics used in mobile devices.
