Abstract : It is apparent that the reactive Q-switching pulsing in the CO2 laser is not restricted to the conventional straight laser where only one mode oscillates at a given instant. In the conventional laser the restriction to one such mode appeared to be the major factor. However, the lengthening of the laser cavity in the multipass CO2 laser provided similar pulse widths and repetition rates. Even at low mirror velocities (about 0.5 cm/sec), pulsing was found to be repetitive in waveform shape and amplitude, whereas under similar conditions in the conventional straight laser, irregular pulsing was observed.
