Abstract :
The mode structures in an optically pumped D2O far-infrared ring laser and a corresponding linear resonator have been compared. While single-mode operation can be obtained over the whole useful pressure range in the ring structure, this is only possible at pressures greater than 8 torr in the linear resonator case. A numerical model predicts quite well the pulse shape, pressure dependence, and influence of the resonator quality in the ring cavity
