摘要

二极管泵浦碱激光器(DPAL)的多种变体最近在美国空军研究实验室(AFRL)进行了演示。这项正在进行的研究工作的重点包括:a)增益(2α)为0.48 cm-1的571W铷(Rb)主振荡器功率放大器(MOPA)， b)同时在795 nm和895 nm处发出激光的铷-铯(Cs)多碱多线(MAML)激光器，c)斜率效率为50%的1.5 kW谐振泵浦钾(K) DPAL。这些试验的共同因素是使用了流动碱试验台。

Advancements in flowing diode pumped alkali lasers

Multiple variants of the Diode Pumped Alkali Laser (DPAL) have recently been demonstrated at the Air Force Research Laboratory (AFRL). Highlights of this ongoing research effort include: a) a 571W rubidium (Rb) based Master Oscillator Power Amplifier (MOPA) with a gain (2α) of 0.48 cm-1, b) a rubidium-cesium (Cs) Multi-Alkali Multi-Line (MAML) laser that simultaneously lases at both 795 nm and 895 nm, and c) a 1.5 kW resonantly pumped potassium (K) DPAL with a slope efficiency of 50%. The common factor among these experiments is the use of a flowing alkali test bed.
