Abstract
A method and a device for detecting a resonant non-linear optical signal induced in a sample including a resonant medium and a non-resonant medium forming an interface is disclosed. The device includes an excitation light beam that intercepts the sample along an optical axis. The device further includes a first optical detection module for detecting a nonlinear optical signal resulting from the interaction of the beam with the sample, and a mirror that reflects the excitation beam. The device further includes a second optical detection module for detecting a nonlinear optical signal resulting from the interaction of the reflected excitation beam with the sample, and a processing module for processing the optical signals, detected by the first and second detection modules. Processing the optical signals includes calculating a difference in the detected signals, the difference being characteristic of a vibrational or electronic resonance of the resonant medium.
