The present work is a comparative study on the laser cleaning of stonework using Nd:YAG lasers at different pulse durations. The ablation rate, the degree of cleaning, and the appearance of the treated surface were studied irradiating a simulated sam

We report the results of the first measurements of the non-linear Kerr refractive index, n2, for LiBaF3 and LiLuF4 crystal hosts, known as prospective UV-emitting tunable laser media when doped with Ce3+ ions. These n2 values (2.7×10-16 and 1.5×10-
