Broadly tunable cw lasers using F(2)(+) centers form the 1.26-1.48 and 0.82-1.07 microm bands.
A cw laser using F(2)(+) centers in KF, continuously tunable over the range 1.26 </= lambda </= 1.48 microm and having a measured slope efficiency of 30%, is described. A selective, two-step photoionization process was used to provide the required F(2)(+)-center density. Also, preliminary report is made of an F(2)(+)-center laser in LiF having ow outputs in excess of 1 W.
