Abstract
A physical model for a flowing four-side pumped alkali vapor laser MOPA system, which considers the saturation effect and amplified spontaneous emission (ASE) and cross-sectional temperature distribution, is established to simulate the output performance of the cesium vapor amplifier. According to the experimental parameters, the simulated result agrees well with the experiment, which demonstrates the validity of this model. Influences of the seed power, the flowing velocity, and the cell length on the amplified power are simulated and analyzed, and a set of optimal operating parameters are obtained. Thus, the model can provide an effective way for designing an efficient side-pumped flowing-gas alkali vapor amplifier.
