Neodymium and gadolinium diffusion in yttrium vanadate

Neodymium and gadolinium diffusion in yttrium vanadate
Lasers based on planar waveguides have recently generated interest for use as scalable high-average-power sources, Here we study the thermal diffusion of Nd3+ and Gd3+ ions in YVO4 in order to obtain the essential diffusion characteristics necessary to calculate the conditions required for fabrication of waveguides suitable for laser action at 1 µm. Nd3+ is studied both for localised doping as the active laser ion and as a potential refractive index modifier. We also choose to study Gd3+ diffusion as an index modifier in order to give the potential for separate control of the index and gain distributions.

Abstract

Lasers based on planar waveguides have recently generated interest for use as scalable high-average-power sources, Here we study the thermal diffusion of Nd3+ and Gd3+ ions in YVO4 in order to obtain the essential diffusion characteristics necessary to calculate the conditions required for fabrication of waveguides suitable for laser action at 1 µm. Nd3+ is studied both for localised doping as the active laser ion and as a potential refractive index modifier. We also choose to study Gd3+ diffusion as an index modifier in order to give the potential for separate control of the index and gain distributions.
