Abstract
An laser system is disclosed for materials processing. The system includes an RF excited, conduction cooled, sealed gas laser. The lasing species in the gas mixture is an isotope of carbon dioxide and in the preferred embodiment is defined by the .sup.13 CO.sub.2 isotope. The use of the .sup.13 CO.sub.2 isotope functions to shorten the rise and fall times of the laser pulses. By this arrangement, the laser may be operated at higher repetition rates with a full depth of power modulation.
