Project Details


The non linear mixing of tunable infrared and visible laser beams is observed at selected interfaces as a function of both infrared and visible frequencies. Vibrational resonances are revealed by scanning the infrared range. Electronic enhancement of these resonances is then observed by varying the visible frequencies.
