Abstract
We present results of the amplified spontaneous emission (ASE) in the system based on dye-doped modified DNACTMA (deoxyribonucleic acid with cetyltrimethyl-ammonium chloride) and lasing in distributed feedback Bragg (DFB) laser composed of a two-layer system: a layer of modified (DNA) polymeric matrix containing dye superimposed on a periodic relief structure formed in photochromic polymer layer. As photoactive and luminescent dye we used the wellknown Rhodamine (Rh 6G). This layer covered a specially designed photochromic polymer layer in which a surface relief grating (SRG) was inscribed by holographic method in order to form a Bragg reflector for photons. Thin film of the DNA-CTMA:Rh6G/photochromic polymer was excited with 6 nanosecond laser pulses at λ = 532 nm wavelength.
