The results of a comparative study of CuBr-laser energy characteristics with a small active volume operating in pulse-periodic mode and dual pump pulses are presented. The advantages of these regimes in the range 5-100 Hz and 5- 100 kHz for output power, the energy generation and efficiency of the laser are shown.
We have detected the separation of generation in active medium of XeCl-laser when the formed beam part was returned back to active medium. We have obtained the anomalous intensity distribution along the cross-section of output in the resonator configurations forming the constrictions between the mirrors. Evidently, we first observed the laser field self-action through the emissivity of particles of the active medium.
