We overview the recent progress in rare-earth-doped fluoride and oxide materials for visible waveguide lasers. Liquid Phase Epitaxy growth and spectroscopy of Eu:KY(WO4)2 and Tb,Gd:LiYF4 epitaxial layers for planar waveguides are presented. Ultrafast Laser Inscription of depressed-cladding channel waveguides in Pr:LiYF4 and their laser operation in the orange are described.
