Abstract
A powerful photo- and thermostable, LiF:F2+ color center laser pumped by radiation at 740 nm or at 683 nm is described. This is the first time an average power as high as approximately 1.4 W and an energy per pulse as high as approximately 100 mJ, with record real efficiency of 53 percent and 28 percent were achieved for a room temperature LiF:F2+ color center laser. Such color center laser, tunable in the 820-1210 nm range, features a number of important advantages over pulsed lasers based on Ti or Cr doped crystals.
