Tunable lasers based on organic dyes are well known and their applications in various branches in physics and chemistry are well established by now. Because of degradation of the dyes under severe atmospheric conditions there is a need to replace the organic molecules by inorganic ions incorporated in a stable inorganic matrix which will have the optical properties and the tunability range of the organic dyes but will not suffer the disadvantage of degradation. One of such materials is single crystal alexandrite doped by trivalent chromium. During the first two years of the research we have shown that spectroscopic properties of CrIII in several singly doped glass-ceramics are comparable to those of alexandrite and the preparation is much easier and more economical. In our present research we are investigating the possibility of extending the tunability range and optimization of the performance of the glass ceramics materials by co-doping with NdIII.Keywords Israel.
