Output pulse shape - and power control of a pulsed co2 laser

摘要

In order to achieve a constant pulse laser output power in a rf - excited, closed, diffusion-cooled, pulsed co.sub.2₂-To maintain the gas discharge laser, then each laser output pulse by means of a pull or a succession of shorter rf - pulses. If the time between the laser output pulses is sufficiently short, so that the power in a pulse of the charge gas discharge - with a slide of a preceding pulse would be reduced, the power is in the rf - pulse trains by changing the duration or the duty cycle of the pulses in the series is altered so that the output pulse power in the laser output pulses is kept constant. Rf - pulses in an arbitrary sequence can have a different duration, the temporal the form of a corresponding laser output pulse tailor.
