Paper Abstract

Time-resolved absorption, gain, and laser spectra were measured for molecules (4- diethylamino-4'-nitrostilbene (DEANS), and 4-dimethylamino-4'-nitrostilbene (DMANS)) with large dipole moments. Tuning ranges of DEANS laser are 612-650 nm, 647-705 nm, 653-708 nm, and 680-705 nm in benzene-acetone mixed solution with volume ratios of 1:0, 5:1, 4:1, and 3:1, respectively. The DMANS laser has a short-cavity, resonatortransient configuration. No spectral shift was observed during laser oscillation. This is consistent with the result of the analysis of lasing by simplified rate equations.
