The firestar v30 manufactured by Synrad Inc. is a 30-W CO2 laser built for use in rugged industrial environments. The air-cooled device is suitable for OEM marking and engraving systems. Its resonator technology produces a circular beam with typical M2 quality of <1.1 in both the near and far fields, and it features a small-diameter bore and high gas fill pressure for rise/fall times of 80 to 90 μs. Long-term power stability is better than ±3%. The laser can be operated from 0 to 100% duty cycle, with power adjusted via a pulse width modulation control.
