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 13CO2 isotope. The use of the 13CO2 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.
