| Abstract: | The output of a high power pulsed CO 2 laser has been produced from a transverse flow CO 2 laser which has particular electrode structure and using the preionized pulse train switched technique. The measurement on the voltage wave, current wave and light wave has been introduced in detail, during from preionization to main discharge and finally, to laser output, and the results of the waves have been analyzed in brief. Moreover, a way of light measurement has been put forward by means of attenuating the light which is based on the light polarization feature. |
