<p>The present invention is directed to a tunable, solid state laser (200) utilizing room temperature, stable, color centers of LiF:F2+** material (202). Also disclosed is a method of lasing. An object of the present invention is to develop and optimize Lif:F¿2?+ thermostabilized active media (202), to propose a method of pumping, and to realize a room temperature, stable and efficient operation of the color center laser (200). These and other objects are achieved by introducing special dopants in the crystal at the stage of crystal growing; applying special regimes of ionizing treatment of the crystal, resulting in thermostabilization of the F¿2?+ centers in Lif crystals and utilizing alexandrite laser radiation for color center crystal pumping with a pump radiation frequency which is appropriate for the selective excitation of the F¿2?+ color centers.</p> |
