✦ Synopsis


Laser tuning spectra, nanosecond gain spectra, and picosecond gain and absorption spectra of I-[p(N,N-dimethylamino)phenyl]-4-(p-nitrophenyl)-l,3-butadiene (DMANPB) are reported. Its permanent dipole moment is found to be larger than 30 D in the lowest excited singlet state. The tuning ranges are 690-725, 695-745, and 705-755 nm in dioxane-acetone mixed solution with volume ratios of 1 :O, 5: 1, and 4: 1, respectively.
