Continuous wave two-photon scanning near-field optical microscopy.
We have implemented continuous-wave two-photon excitation of near-UV absorbing fluorophores in a scanning near-field optical microscope (SNOM). The 647-nm emission of an Ar-Kr mixed gas laser was used to excite the UV-absorbing DNA dyes DAPI, the bisbenzimidazole Hoechst 33342, and ethidium bromide in a shared aperture SNOM with uncoated fiber tips. Polytene chromosomes of Drosophila melanogast...
متن کاملNear-field two-photon nanolithography using an apertureless optical probe
Near-field two-photon optical lithography is demonstrated by using ;120 fs laser pulses at 790 nm in an apertureless near-field optical microscope, which produces lithographic features with ;70 nm resolution. The technique takes advantage of the field enhancement at the extremity of a metallic probe to induce nanoscale two-photon absorption and polymerization in a commercial photoresist, SU-8. ...
متن کاملImaging of Single Photon Emitter Fluorescence and Photon Antibunching
In this experiment we demonstrate the Confocal Microscope fluorescence imaging of various single photon emitters like carbon nanotube, quantum dots and color centre in nano-diamonds. We also measure their spectrum to characterize them. Finally we use the Hanbury Brown and Twiss Setup to test if the photons emitted from our source has antibunching properties.
متن کاملAn overview of scanning near-field optical microscopy in characterization of nano-materials
Scanning Near-Field Optical Microscopy (SNOM) is a member of scanning probe microscopes (SPMs) family which enables nanostructure investigation of the surfaces on a wide range of materials. In fact, SNOM combines the SPM technology to the optical microscopy and in this way provide a powerful tool to study nano-structures with very high spatial resolution. In this paper, a qualified overview of ...
