Solid-state dye laser
A solid-state dye laser is a solid-state lasers in which the gain medium is a laser dye-doped organic matrix such as poly(methyl methacrylate), rather than a liquid solution of the dye. These lasers are also referred to as solid-state organic lasers and solid-state dye-doped polymer lasers.
SSDLs were introduced in 1967 by Soffer and McFarland.
