Lasing process inside gas-state media of a diode-pumped alkali laser

A diode-pumped alkali laser (DPAL) provides the significant promise for high-powered performances. For an end-pumped DPAL, both the absorption and the lasing distribution crucially affect the output physical features. In this report, a mathematical model is introduced for examining the absorption and lasing processes of the gas-state media by using a segmental approach. The energy transmission inside the oscillator has been theoretically analyzed for construction of a reciprocating regime which is based on the self-consistency principle. Basically, the conclusion can be extended to any end-pumped laser configurations.
