“…Recently, diode-pumped alkali lasers (DPALs) have attracted considerable attention due to the potential for realization of high-powered lasers [1][2][3][4][5]. Generally, the DPAL is a typical three-level laser using atomic alkali (K, or Rb, or Cs) vapor as the gain medium, whose quantum defect is much smaller than those of most of the conventional lasers [6][7][8]. Furthermore, the output linewidth of a DPAL is extremely narrow, the laser medium is nontoxic, and the DPAL system is generally compact [9][10][11].…”

A diode pumped alkali laser (DPAL) provides a significant potential for construction of high-powered lasers. To realize the scaling of a DPAL, heat management should be optimized. In this paper, a new kind of gas-flowing DPAL was proposed, in which a small cross-flow fan with diameter of 80 mm was set in the center of a cylindrical vapor cell whose diameter is 125 mm. The gain medium of cesium and the buffer gas of ethane were filled in the vapor cell with the total pressure is about 1 atmosphere. A mathematical model was constructed to systematically study the influence of the rotate speed, the heating temperature on the internal temperature distribution, and the output features of the laser.

Mixing cross sections of Cs between the 62P1/2 and 62P3/2 levels and quenching cross sections from these levels to the ground state 62S1/2 were measured, with methane, ethane, and propane as collision partners. We excited Cs to the 6P3/2 level with a tunable nanosecond pulse laser and measured the fluorescence at the 62P1/2 level. The measured mixing cross sections with methane, ethane, and propane were (1.39 ± 0.16), (5.67 ± 0.85), and (7.91 ± 0.93)×10−15 cm2, respectively, and the statistically averaged quenching cross sections were (1.5 ± 0.25), (10 ± 2.0), and (25 ± 5.3)×10−18 cm2, respectively. The quenching cross section of Cs-propane is reported for the first time.
