Efficient Potassium Diode Pumped Alkali Laser Operating in Pulsed Mode

Abstract

This paper presents the results of our experiments on development of the efficient hydrocarbon free Diode Pumped Alkali Laser based on potassium vapor buffered by He gas at 600 Torr. A slope efficiency of more than 50% was demonstrated with total optical efficiency about 30%. Such result was achieved by using a narrowband diode laser stack in pulsed model as a pump source that allows to avoid limiting thermal effects and ionization.
