Abstract This work demonstrates the spectral and amplified spontaneous emission (ASE) properties of a new chalcone laser dye material of 1-(4-methylsulfonyl phenyl)-3-(4-N, N dimethyl amino phenyl)-2-propen-1-one (MSPPP). The absorption, fluorescence, Stokes’ shift and quantum yield were obtained using different organic solvents. The energy band gap was calculated and compared with that of 3-[4-(dimethylamino) phenyl]-1-phenyl-(2E)-propen- 1-one (DAPPP). These include absorption, fluorescence, stokes shift, and amplified spontaneous emission (ASE). The absorption spectra of MSPPP showed a wavelength band in the range 403–427 nm, whereas the fluorescence spectra exhibited a band at 472–533 nm. ASE was observed under pump pulse laser excitation, and the wavelengths were attuned from 511 to 548 nm.

We demonstrated that well resolved and intense spectral lines can be obtained by single pulse laser excitation underwater if recording only secondary plasma emission using large acquisition gate widths.
