“…During the experiment, the temperature of the GDT wall was kept constant by the external heating [14]. Since the self-heating of the active medium is negligible under the described conditions, the gas temperature can be approximately considered constant along the GDT radius and equal to the wall temperature.…”

“…In [13], the increased radiation pulse duration has been achieved using the pump by a train of dissociation pulses and a subsequent single excitation pulse. The stable temperature was provided by the external heating [14] in order to maintain the stationary temperature regime when the delay between the end of the train and the excitation pulse is varied. It was shown that the laser generation is observed even with when the delay between the last pulse of the train and the excitation pulse reaches 2 milliseconds.…”

We study a non-typical excitation mode of the copper bromide active medium using the kinetic model. The active medium is pumped by the pulse train and the laser generation is obtained in the subsequent single excitation pulse. Such mode allows one to obtain the laser generation pulse with the extended duration by increase in the pause duration after the pulse train. The relaxation processes during the pause are studied in order to explain such effect. It is shown that this operation mode can also be used to obtain the superradiance and amplification pulses of the extended duration that is of interest for active optical systems. Based on the comparison with the experimental results, new fundamental results are obtained regarding the copper bromide kinetics in the active medium.
