Stable mode-locking and pulse coupling of a longitudinal discharge CO2 laser, using a single electrooptic element, was demonstrated successfully. The experimental results and data on the effect of modulator detuning and coupling factor variations are presented. Similar experiments were performed with a CO2 TEA laser in which loss-locking was obtained using the internal electrooptic element as an AM modulator. However, attempts at phase-locking were unsuccessful. Results of a detailed investigation of the discharge properties of the TEA laser are presented. The processes involved in mode- locking and their bearing on the observed results are discussed.
