A diode-pumped alkali lasers (DPAL) is a new type of laser source which can offer laser radiation with high efficiency and tiny thermally-induced effects in the near-infrared wavelength region. By constructing a theoretical algorithm through uniting the kinetic, heat transfer, and fluid dynamic procedures together, the thermal features and output characteristics of a DPAL are systematically evaluated for both the static and flowing-gas statuses. The corresponding temperature distributions are calculated for different powers of a pump beam. The results are thought to be useful for realization of a high-powered DPAL in the future.
