Abstract : This report describes an efficient, four-level, blue-green, excimer-pumped laser which is operable at room temperature. The laser element includes a CaWO4 crystal which has been codoped with trivalent thulium activator ions and divalent ytterbium sensitizer ions. Energy is transferred from the absorbing Yb2(+) ions to the Tm3(+) ions and the laser transition is from the 1D sub 2 multiplet to the ground 3 F sub 4 of the Tm3(+) ion. This transition terminates on an excited state; therefore, the laser action is four-level.
