<p>A gel composition for use as carrier of dyes for use in dye laser systems is disclosed. At rest the composition is a rigid, transparent gel which is insensitive to air or moisture, which is able to overcome heat accumulated with laser use, and which thins to a low viscosity when restricted or subjected to shearing and which quickly resolidifies to a rigid gel when shearing is reduced. More specifically, the carrier gel is comprised of layered mixed metal hydroxide particles, which may be produced by hydrolyzing a mixture of the alkoxides of magnesium and aluminum. The carrier gel is useful in dye laser systems as a solid or semi-solid, fixed or fluidized carrier of very low solids content. The dye laser systems have therapeutic diagnostic uses.</p> |
