Crystal growth and characterization of epitaxial layers of laser and nonlinear optical materials for thin-disk and waveguide laser applications

This paper summarizes the main results we obtained in our laboratories in relation with crystalline layers obtained by Liquid Phase Epitaxial growth of lanthanide doped KLu(WO4)2 and Nb:RbTiOPO4 grown on KLu(WO4)2 and RbTiOPO4 substrates, respectively. Macroscopic defect free epitaxial layers were grown and characterized in terms of their compositional homogeneity, structural stress in the layer/substrate interface and laser and waveguiding performances.
