    We configure a fiber-laser based dual-comb spectrometer to measure the O2 delta band (1260 nm) in addition to CO2 and CH4 absorption features (1600 nm).

    We propose that Raman excitation can generate singlet oxygen in water environments without intervention of photosensitizers. Preliminary Raman experiments using continuous wave laser light at 405 nm validate the hypothesis

  3. (, Journal of the Optical Society of America)
    Optica Publishing Group (Ed.)
    This contribution introduces a pump-probe photothermal mirror Z-scan method to measure the thermal quantum yield, the thermal diffusivity, and other photothermal parameters of an opaque solid. The focusing of a pump beam of light onto the sample generates thermoelastic surface distortions. The distorted surface acts as a mirror affecting the diffraction pattern of a reflected probe beam yielding the experimental signal. Scanning the focusing lens produces a single peak photothermal mirror Z-scan signature. The amplitude and time evolution of the signal determines the sample’s photothermal properties. The method is used to analyze gallium arsenide and silicon plates, obtaining good agreement with previous studies.
