Abstract: | The behaviour of a rf-excited waveguide CO2 laser in the pulse regime is studied experimentally. The specific time sections of the pulse have been defined and described
in detail. The output pulse evolution versus input power, pressure of the laser mixture, output coupling, repetition frequency
and pulse width has been investigated. The spectral content of the pulse has been analysed. A model explaining the effect
of laser tuning during the pulse duration is given. The ultrahigh pulse (UHP), defined as the pulse for which the bulge effect
occurs, is predicted.
