Abstract: The nonlinear Kerr refractive index n2 was determined in several crystal hosts, suitable for Ce3+ doping to obtain tunable laser emission in the UV (LiBaF3, LiLuF4, LiCAF, SrAlF5) and in the KMgF3, suitable for Yb2+ doping, a potential laser material in blue region. These parameters were measured by means of Z-scan measurements at 1064 nm and 532 nm, using picosecond laser pulses. The materials under test didn\’t exhibit two photon absorption effects, within the experimental sensitivity limits. The characterization of these new optical materials is important in view of the development of high peak power laser oscillators and amplifiers.
