Paper Abstract

We report on efficient third-harmonic generation (THG) with large spectral and angular bandwidths in polymer thin films doped with conjugated organic molecules. Using the efficient THG exhibited by these organic films, we demonstrate real-time, time-gated, direct imaging of objects immersed in highly scattering media by using femtosecond pulses tuned at the eye-safe and telecommunication-compatible near-infrared spectral region (1550 nm). By using a low cost detection system we resolved THG time-gated images of objects immersed in media with a scattering attenuation of 14 mean-free paths, equivalent to an attenuation of six optical densities.
