 note = {A numerical simulation of an optically pumped, multimode D_2O laser was carried out based on Lamb’s semiclassical laser theory. The numerical code includes the dispersion effect of the laser medium (D_2O gas in the cavity) in order to simulate the strength of mode coupling accurately. As a result, multiple-longitudinal-mode oscillations around the Raman resonance frequency were obtained that are roughly in agreement with experimental observations. Energy spectra of the D_2O laser emission obtained by the simulation were compared with those of the experimental results for various D_2O gas pressures. By including the dispersion effect, temporal variations of mode frequencies were calculated. In addition, resonant pumping was examined to obtain spectrally narrow outputs by tuning a frequency of a pump CO_2 laser pulse to the line center of the absorption band of D_2O molecules.},
