cze	Optické operace s chromofory na bázi 4,5-dikyanimidazolu ukotvených v polymethylmetacrylátových matricích.	Byly studovány fotoindukované absorpce, bireference a SHG i polymethylmetacrylátových filmech dopovaných orga. chromofory na bázi 4,5-dikyanoimidazolu (ca 5%). Vzorky byly získány jako několik mikrometrů tenké filmy metodou spin-coating. Měření byla provedena metodou Senarmont při vlnové délce 1150 nm, fotoindukovaná absorpce byla studována v rozsahu 250-700 nm pomocí 300 mW cw 532 nm laseru. Fotoindukovaný optický efekt byl studován pomocí 1064 a 532 nm koherentního laserového pulsu.	chromofor; imidazol; polymethylmethacrylát; NLO
eng	Optical Operation by Chromophores Featuring 4,5-Dicyanoimidazole Embedded within Poly(methyl methacrylate) Matrices	We have studied photoinduced absorption, birefringence, and optical second-harmonic generation in poly(methyl methacrylate) (PMMA) films doped by organic chromophores featuring 4,5-dicyanoimidazole in the weight content equal to 5%. The samples were obtained as films of several micrometers thickness by the spin-coating method on a quartz substrate. Measurements of the optically induced birefringence were done by the Senarmont method at wavelength 1150 nm, and photoinduced absorption was studied in the spectral range 250-700 nm under optical treatment by 300 mW cw 532 nm laser. Photoinduced optical effects were studied by bicolor 1064 and 532 nm coherent laser pulses.	chromophore; imidazole; polymethylmethacrylate; NLO
