A promising nonlinear crystal for third harmonic generation in UV: Ca(BO)FDeveloping large laser grade cubic rare-earth sesquioxides (REO, RE=Sc,Y,Lu) single crystals doped with Ybions stands as one of the most challenging endeavours of today's crystal growth [1,2], essentially because of...
One of these new frontiers opened by the laser was the field of nonlinear optics. In 1961, Franken et al. were the first to report the observation of second-harmonic generation from a quartz crystal, using ruby laser light. Third-harmonic generation (THG) was soon discovered by Terhune and...

Nonlinear processes are often governed by selection rules imposed by the symmetries of the molecular configurations. The most well-known examples include the role of centrosymmetry breaking for the generation of even harmonics, and the selection rule related to the rotational symmetry in harmonic genera...
