Coherent, Inc. (Santa Clara, CA) has added the new DIAMOND E-250 to its E Series CO2 laser family. The power range for the Coherent E-Series product line extends from 150W to 1000W. 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. 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.
