Paper Abstract

Nuclear-pumped lasers (NPLs) potentially offer an attractive method for high power laser applications such as a space power beaming. However, thermal gradients created by the pumping of the ion medium are producing a dynamic thermal blooming which must be understood and controlled for accurate beam control and focusing. In this paper, basic experimental studies of blooming under a variety of conditions are presented. It is shown that one promising approach for reducing the effect is to employ a combined volume-wall pumping technique.
