| 1 | Deleterious processes of a diode-pumped cesium vapor hollow-core photonic-crystal fiber laser显示文摘A diode-pumped alkali laser(DPAL) provides the significant promise for high-powered performances. In this paper, a mathematical model is introduced for examination of the kinetic processes of a diode-pumped cesium vapor hollow-core photonic-crystal fiber(HC-PCF) laser, in which the cesium vapor is filled in the center hole of a photonic-bandgap fiber instead of a glass cell. The influence of deleterious processes including energy pooling, photo-ionization, and Penning ionization on the physical features of a fiber DPAL is studied in this report. It has been theoretically demonstrated that the deleterious processes cannot be ignored in a high-powered fiber-DPAL system. | Guofei An You Wang Juhong Han He Cai Zhigang Jiang Ming Gao Shunyan Wang Wei Zhang Hongyuan Wang Liangping Xue Jie Zhou | 2016 | High Power Laser Science and Engineering2016，4，4： | 0 |
| 2 | Experimental evaluation of temperature distribution of a vapor cell using a Hilbert transform procedure显示文摘A diode-pumped alkali vapor laser(DPAL) is one of the most promising candidates of the next-generation high-powered laser source. As the saturated number density of alkali vapor is highly dependent on the temperature inside a vapor cell,the temperature distribution in the cross-section of a cell will greatly affect the homogeneity of a laser medium and the output characteristics of a DPAL. In this paper, we developed an algorithm based on the regime concluding quasi-Hilbert transform to evaluate the phase aberration of a wavefront when the probe beam passes through the vapor cell placed in one arm of a Mach–Zehnder interference setup. According to the theoretical algorithm, we deduced the temperature distribution of a cesium vapor cell for different heating conditions. The study is thought to be useful for development of a high-powered laser. | He Cai You Wang Ming Gao Wei Zhang Zhigang Jiang Juhong Han Guofei An Shunyan Wang Liangping Xue Hongyuan Wang Jie Zhou | 2016 | High Power Laser Science and Engineering2016，4，4： | 0 |
