Abstract
Composing a slab-waveguide by spin-coating dye-doped organic monomer onto a glass substrate under UV irradiation to be polymer, frequency selective lasing is observed by the side pumping of an interference pattern of pump beam. The thin-film slab-waveguide consists of Rhodamine B (Rh-B)-doped thio ether methacrylate (TEMA) with the thickness of approximately 2 μm. Pumping the thin-film by the interference pattern of Nd:YAG (SHG) 530 nm laser with the gain period Λ of 15 μm, the lasing output is selectively observed near 610 nm, in contrast to no lasing under a uniform pumping. Both effects of the pump energy on the lasing output and of the gain period on the wavelength are also described.
