Optical injection unlocking for cavity ringdown spectroscopy.
Continuous wave cavity ringdown spectroscopy requires a rapid termination of the injection of light into the cavity to initiate the decay (i.e., ringdown) event. We demonstrate a technique that accomplishes this through pulsed optical injection of a second laser into the main laser, resulting in 20-100 MHz frequency shifts in the otherwise cavity-locked main laser sufficient to create ringdown ...
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 ...

متن کاملInfrared cavity ringdown spectroscopy of jet-cooled polycyclic aromatic hydrocarbons.
Infrared absorption spectra of the CH stretching region were observed for naphthalene, anthracene, phenanthrene, pyrene, and perylene using a heated, supersonic, slit-jet source and cavity ringdown spectroscopy. Band positions and intensities recorded with 0.2-cm-1 resolution were compared with previous gas-phase and argon matrix isolation experiments, as well as theoretical calculations. The l...
