Abstract
A solid-state laser emitting material for use in conjunction with a light source includes a polymer matrix functioning as host materials, containing laser dye of rhodamine 590 or rhodamine 610 as gain materials and nano-submicron particles as scatters therein. The lowest lasing threshold of the laser emitting material is approximately 5 mJ/cmfor 585 nm emission and 2 mJ/cmfor 630 nm emission.
