We report a room temperature tunable color center distributed feedback (DFB) laser using stabilized F2+** centers in LiF (LiF:F2+**) as a gain medium. Tunable oscillation of LiF:F2+** DFB lasing was achieved in the near infrared region (882–962 nm) with a lasing linewidth of less than 0.2 cm-1. Also the lasing threshold and slope efficiency with respect to pump energy were found to be 1.2 mJ and up to 3%, respectively. © 2004 American Institute of Physics.
