Abstract : On the line of a previous work on the spectral properties of some of heteroaryl chalcone, the effect of medium acidity and photoreactivity of 3-(4-dimethylamino-phenyl)-1-(2,5-dimethyl-thiophen-3-yl)-propenone (DDTP) has been investigated in dimethylformamide and in chloromethane solvents such as methylenechloride, chloroform and carbon tetrachloride. The dye solution (ca. 5 × 10 -4 mol·L -1 in DMF) gives a good laser emission in the range 470-560 nm with emission maximum at 515 nm upon pumping by nitrogen laser (λ ex = 337.1 nm). The laser parameters such as gain coefficient (α), emission cross section (σ e) and half life energy (E 1/2) at maximum laser emission are also determined.
