We propose an approach, based on wavelet prism decomposition analysis, for correcting experimental artefacts in a coherent anti-Stokes Raman scattering (CARS) spectrum. This method allows estimating and eliminating a slowly varying modulation error f

For noninvasive characterization of chemical species or biological components within a complex heterogeneous system, their intrinsic molecular vibrational properties can be used in contrast mechanisms in optical microscopy. A series of recent advance

We report a theoretical description and experimental implementation of multiplex coherent anti-Stokes Raman scattering (M-CARS) microspectroscopy using a picosecond pump beam and a femtosecond Stokes beam. The effect of the chirp in the Stokes pulse

In narrow-bandwidth coherent Raman scattering (CRS) microscopy, efficient signal generation is accompl ished with two-color laser sources providing synchronized pico second pulses whose frequency difference and spectr al widths match the molecular Ra

The excited state properties of magnesium(II)-tetrabenzoporphyrin (Mg-TBP) were studied by using intensity dependent transmission (non-linear absorption), ps-transient absorption and time resolved luminescence spectroscopy. It was found that there is

We have developed a time-correlated single-photon timing nonlinear fluorometer for recording the fluorescence decay times and rotational correlation times of molecular probes using 120 fs regeneratively amplified Ti:Sapphire laser excitation via simu

A series of advances over the past decade have made the combination of coherent Raman scattering (CRS) with optical microscopy a highly sensitive and chemically selective tool for the label-free and noninvasive analysis of chemical species or biologi

A time-resolved coherent anti-Stokes Raman scattering (CARS) microscope allows three-dimensional imaging based on Raman free induction decay of molecular vibration with no requirement for labeling of the sample with natural or artificial fluorophores

A stimulated Raman scattering microscope with near-infrared picosecond laser pulses at high repetition rates (76 MHz) and radio-frequency lock-in detection is accomplished. Based on stimulated Raman loss detection, we demonstrate noninvasive point-by
