Scanning absorption nanoscopy with supercontinuum light sources based on photonic crystal fiber.
We have experimentally demonstrated a scanning absorption nanoscopy system combining a near-field scanning optical microscope with an absorption spectroscope using supercontinuum radiation generated by coupling a mode-locked Ti:sapphire pulse laser to a nonlinear photonic crystal fiber as a light source. For the performance test of the system, the absorption spectrum and near-field absorption image of Rhodamine 6G were observed. As this system allows us to investigate the absorption properties and distribution of materials with high spatial resolution, it is expected to be effectively applied in various research areas.
