We report a new technique to increase the stability of mode-locked pulses from a TEA-CO/sub 2/ laser. It consists essentially in the mode locking of a hybrid laser. Moreover, with the low-pressure cw gain cell operating, the pulsewidth varies as ..cap alpha../sup -1.1/, where ..cap alpha.. is the modulation parameter, in contrast to the ..cap alpha../sup -0.5/ dependence without the cw gain module. This permits easy tuning to the pulse width between 1.8 and 10 nsec. A model is presented that agrees well with our experimental results.
