The simultaneous action of 355-nm and 1064-nm laser lights with 10-ns duration gave substantially larger photocurrent signals than those when the 355-nm light acted alone for various aromatic molecules in n-heptane. The photocurrent signal tended to be larger for a larger molar absorptivity of a molecule. The enhancement of the photocurrent signal induced by the additional action of the 1064-nm light was correlated with the excess excitation energy as well as the 1064-nm pulse energy.
