CARS multiplex microscopy system

Abstract

A CARS multiplex microscopy device for analyzing a sample (Sample) comprising: a laser source (LS) adapted to emit a primary beam (FP) having a first wavelength in the form of pulses (IL1) with a so-called primary power; an optical fiber (F) having fewer than ten modes, said pulses propagating in the optical fiber (F) in an anomalous dispersion regime to generate, from the primary beam, an output beam (FSC) having a plurality of second wavelengths forming a supercontinuum (SC), and said first wavelength, the second wavelengths being generated by nonlinear conversion of the first wavelength; an optical system (MO) adapted to focus the output beam on said sample, so as to generate an anti-Stokes beam (STK) by stimulated Raman effect induced by at least one of the second wavelengths and the first wavelength present in the output beam;a photodetector (Det) adapted to detect the anti-Stokes beam.
