| Outline of Final Research Achievements |
Heterodyne-detected sum frequency generation (HD-SFG) has been applied only to "unburied" interfaces such as air/liquid and air/solid interfaces, because the optically-thick bulk makes it difficult to determine the phase of an electric field, which hinders the heterodyne detection. Here we report that HD-SFG for "buried" interfaces can be carried out by the precise measurement of the bulk thickness and the rigorous expression of the signal electric field.
