Lasers based on planar waveguides have recently generated interest for use as scalable high-average-power sources, Here we study the thermal diffusion of Nd/sub 3//sup +/ and Gd/sub 3//sup +/ ions in YVO/sub 4/ in order to obtain the essential diffusion characteristics necessary to calculate the conditions required for fabrication of waveguides suitable for laser action at 1 /spl mu/m. Nd/sub 3//sup +/ is studied both for localised doping as the active laser ion and as a potential refractive index modifier. We also choose to study Gd/sub 3//sup +/ diffusion as an index modifier in order to give the potential for separate control of the index and gain distributions.
