A numerical modeling technique has been used to study the dynamics of generation of induced emission in a series of organic compounds: coumarin (7-amino-4-methylcoumarin and 6-bromo-3-(4-(4-bromophenyl) thiazole-2-yl)-coumarin) and rhodamine 6G. The effect of concentration on the lasing wavelength (rhodamine 6G) has been elucidated, along with the lasing capability of 7-amino-4-methylcoumarin at different pump pulse durations. The reasons for the absence of lasing in 6-bromo-3-(4-(4-bromophenyl)thiazole-2-yl)-coumarin have been investigated.
