Abstract: Five heptamethine cyanine dyes containing a diphenylamino group at the meso position in their bridge chain were synthesisedTheir absorption spectra and fluorescence emission spectra were determinedThe lasing properties of these dyes, including the tuning range, the center laser wavelength, and the conversion efficiency were examined with the pump source of the frequency-doubled YAGlaser(532 nm).

Key words: Heptamethine cyanine, Absorption spectrum. Fluorescence emission spectrum, Lasing property
