Predicted spectral linewidths have been computed as a function of the laser and physical parameters of a pulsed high-gain three-level multimode self-terminating laser. In particular, the values of the parameters that yield minimum widths have been obtained because of their applications in the fields of holography and lidar. The model previously developed by the author for the cuprous chloride laser and the approximate parametric values found are used as a basis for these computations, since this laser combines visible radiation, high average power, and intrinsically narrow hyperfine lines. It is found that a temporal minimum width occurs prior to termination of the laser pulse for all parameter combinations. This temporal minimum width increases with increased temperature and Cu density, decreases with increased electron-excitation pumping rate from the ground to the upper excited state, and is virtually independent of the homogeneous FWHM. Quantitative relations between the coherence length and the spectral linewidth are derived for several waveforms.
