Abstract

The getting problems of UV and VUV laser action on the base of trivalent rare-earth ions activated crystals and the opportunities of upconversion pumping are discussed. The data of spectroscopical studies of stepwise multiphoton excitation of 4P'5d mixed configuration of Nd3, Pr3 and Ce3 ions in LiLuF4 and LiYF4 crystals are reported. The selection criterions of an intermediate 4f-state and a range of allowable pumping photon energies for the stepwise multiphoton excitation are proposed.
