By a judicious choice of operating conditions, we have succeeded in achieving a very high gain operation of a cw CO{sub 2} laser. It is found that for gain above threshold values of more than 5.2, the emission of the laser breaks down, giving rise to oscillations in space as well as low-frequency oscillations in time (1.6 kHz, while the free spectral range of the laser cavity is 50 MHz). The spatial and temporal instabilities that coexisted were found to have a critical dependence on the gain above threshold values.
