Popis:	The influence of the atomic lifetime and Raman field strength on the gain and laser threshold in noninverted atomic systems is studied. Results show that to achieve useful gain in such a system, it is necessary to use a sufficiently intense Raman field, atoms with a long lifetime for the lower active levels, and a small cavity loss.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.
