“…Pumped configurations have played an important role in enhancing the laser power of DPALs. Up to now, numerous experimental studies on DPALs with different pumped configurations were performed, including single-end pumped configuration [1,3,4,8], double-end pumped configuration [2,7], single-side pumped configuration with stable resonator [5] and unstable resonator [6]. Their corresponding models were set up by [9][10][11][12][13][14][15] and agreed well with the experimental results.…”

“…These advantages make DPALs one of the most promising candidate technologies for highpowered lasers with both good beam quality and a compact size [14]. Recently, Russian researchers have achieved an output power of approximately 1 kW in a cesium laser with a two-side pumped configuration [15]. They report an optical-to-optical efficiency of as high as 48 %.…”

Diode-pumped alkali lasers (DPALs) have undergone rapid development to become one of the most promising candidates for use as high-power laser sources in recent years. Relaxation oscillation (RO) is a common phenomenon related to the dynamic process in the time domain. Sometimes, it is applied in parameter measurement, but sometimes it should be eliminated to ensure stable output. In this paper, we develop a kinetic model to study the RO features of a DPAL, which are different from those of a conventional solid-state laser. The results reveal that the cell temperature, buffer gas pressure, pumping power, cavity length, and reflectance of an output coupler affect the characteristics of ROs. Among these parameters, the cell temperature and the pumping power exert relatively strong influences on the waiting time of the first spike in the RO. Additionally, the cavity length cannot markedly affect the peak value of the laser intensity. These new analyses should prove useful for understanding the dynamic process of DPAL oscillation and for the future design of a steady high-powered DPAL.

“…The flow can both remove the excessive heat and replenish density of neutral alkali atoms required for gain and lasing. A recent experiment on lasing in the flowing Cs-CH 4 -He mixture with high power pump 51 demonstrated about 48% optical-to-optical efficiency at kW power level that showed effective mitigation of these limiting effects. The authors of this work used end pumping of the cell with flowing gain medium by multiple diode laser stacks with total power about 2 kW and obtained the output laser power close to 1 kW.…”

Review of alkali laser research and development

Abstract. In this review we present an analysis of optically pumped alkali laser research and development from the first proposal in 1958 by Schawlow and Townes to the current state. In spite of the long history, real interest in alkali vapor lasers has appeared in the past decade, after the demonstration of really efficient lasing in Rb and Cs vapors in 2003 and the first successful power scaling experiments. This interest was stimulated by the possibility of using efficient diode lasers for optical pumping of the alkali lasers and by the fact that these lasers can produce a high quality and high power output beam from a single aperture. We present a review of the most important achievements in high power alkali laser research and development, discuss some problems existing in this field, and provide future perspectives in diode pumped alkali laser development.
