Miniature laser elements based on color centers with an extremely low lasing threshold
Abstract
A lasing medium has been developed on the basis of lithium fluoride single crystals with an extremely high concentration of active centers, F2 and F3(+), which reaches the region of concentration quenching. The coloring technique used here has made it possible to reduce sharply the concentration of parasitic cluster centers and, therefore, optical losses in the medium. The lasing threshold for the F2 and F3(+) centers is 4 and 60 kW/sq cm, respectively.
