Time duration of the output pulse of electron-beam-pumped CdS laser was investigated. It increased with increase of the excitation current density and was of the order of 100 ns at the beam voltage of 25 kV. It was shown experimentally that the quenching of the laser oscillation is due to the rise of the threshold current density as the result of the temperature rise in the active region of the crystal. The expression for the duration of laser oscillation based on this model was derived and compared with the experimental results. The dependence of the duration on the excitation current density was explained by this model.
