ABSTRACT:
A novel dye laser comprises a laser dye solution comprising a conductive polymer having the chemical formula ##STR1## wherein R comprises (C.sub.1 -C.sub.10)alkyl, R' is the same or different from R and comprises alkyl, substituted alkyl, benzyl, or substituted benzyl, such as --(CH.sub.2).sub.n CH.sub.3 or CH.sub.2 C.sub.6 H.sub.4 (CH.sub.2).sub.n Y, wherein Y is O-alkyl, alkyl, alkenyl or alkynyl and n is greater than 1 and up to 200, and for structure IV R" is the same or different from R and comprises (C.sub.1 -C.sub.10)alkyl, and x is greater than about 20, and a non-aqueous solvent; the solvent being substantially unable to chemically react with the polymer and to absorb and emit light at a wavelength similar to the conductive polymer, and a pumping energy source operably coupled therewith and capable of producing stimulated emmission of the dye solution.
A laser device, comprising a solid body of the conductive polymer described above, and a host polymer, the host polymer being unable to chemically react with the polymer and unable to absorb and emit light at a wavelength similar to the conductive polymer, means for pumping the body to generate light therein, and means for creating distributed feedback of the light to achieve a substantially coherent beam of light which is emitted from the body.
