Spatial-angular characteristics of radiation from flashlamp-pumped dye lasers in different temperature conditions of active elements

摘要

Investigations were performed of spatial-angular characteristics of radiation from flashlamp-pumped dye lasers in different temperature conditions of active elements. It was found that the laser beam divergence depends on the parameters of the active element and cooling conditions. A prerequisite for ensuring a high directionality of radiation from these lasers operating in the repetitively pulsed regime was shown to be temperature stabilization of the active element and coolant.
