Abstract
A system for measuring the absorption of a laser radiation by a sample is provided. The system comprises: •(i) a pulsed laser source, suitable for emitting pulses at a repetition frequency fand arranged so as to illuminate the sample; •(ii) an AFM probe arranged so as to be able to be placed in contact with the region of the surface of the sample on one side, the AFM probe having a mechanical resonance mode at a frequency f; and •(iii) a detector configured to measure the amplitude of the oscillations of the AFM probe resulting from the absorption of the laser radiation by the region of the surface of the sample, characterized in that it also comprises a translation system designed to displace the sample at a frequency f.
