Development of high power cw KCl:Li (F+2)Acolor center lasers

We have developed a KCl:Li (F+2)A color center laser which produces more than 1.2 W of cw laser power, over a factor of 3 greater than the highest power previously reported. This paper contains the results of this study, and presents guidelines for preparing laser crystals to routinely and reproducibly generate these high powers.
