Title: Multiple stimulated emission fluorescence photoacoustic sensing and spectroscopy

Abstract

Multiple stimulated emission fluorescence photoacoustic (MSEF-PA) phenomenon is demonstrated in this letter. Under simultaneous illumination of pumping light and stimulated emission light, the fluorescence emission process is speeded up by the stimulated emission effect. This leads to nonlinear enhancement of photoacoustic signal while the quantity of absorbed photons is more than that of fluorescent molecules illuminated by pumping light. The electronic states' specificity of fluorescent molecular can also be labelled by the MSEF-PA signals, which can potentially be used to obtain fluorescence excitation spectrum in deep scattering tissue with nonlinearly enhanced photoacoustic detection. In this preliminary study, the fluorescence excitation spectrum is reconstructed by MSEF-PA signals through sweeping the wavelength of exciting light, which confirms the theoretical derivation well.

  • The dispersed fluorescence (DF) and stimulated emission pumping (SEP) spectra of acetylene originating from single rovibronic levels of the {ital {tilde A}} {sup 1}{ital A}{sub {ital u}} state were measured with resolutions of 30 and 0.5 cm{sup {minus}1}, respectively, in order to examine the vibrational level structure of the electronic ground {ital {tilde X}} {sup 1}{Sigma}{sup +}{sub {ital g}} state. The SEP spectra revealed that the number of vibrational levels under each peak in the DF spectra increases with vibrational energy from a single vibrational level below 8000 cm{sup {minus}1} to as many as ten vibrational levels above 16 500more » cm{sup {minus}1}. Taking account of the fact that a peak in the DF spectrum in the high energy region is composed of more than one level, a DF peak is called a {ital feature} {ital state} (or a feature). In the DF spectra from two {ital trans}-bending levels ({ital v}{sub 3}=2 and 3) of the {ital {tilde A}} state a total of 140 DF features between 5 700 and 21 200 cm{sup {minus}1} were detected and long progressions in the {ital trans} bend ({ital v}{sup {double prime}}{sub 4}=6 --18) and CC stretch ({ital v}{sup }{sub 2}=0 --6) were identified.« less
  • Photoacoustic detection has been used to monitor a stimulated emission pumping process in p-difluorobenzene. Using the A /sup 1/B/sub 2u/5/sup 1/ state as an intermediate, several vibrational levels of the ground electronic state were populated. The photoacoustic method is an attractive alternative to other detection techniques because of its sensitivity, simplicity, and its ability to differentiate between stimulated emission pumping and excited state absorption. An example of excited state absorption in aniline is given.
  • The fluorescence quantum efficiency of oxazine 1 perchlorate in 1,2-dichloroethane was measured with photoacoustic spectroscopy in which fluorescence quenching was used. The measurement shows that the relation between the fluorescence quantum efficiency and the concentration of solution of oxazine 1 in 1.2-dichloroethane is obviously different from that of some conventional dyes and solid fluorescence materials. A theoretical molecular energy transfer model was derived; it is in good agreement with the experimental results.
  • Polarized /sup 4/F/sub 3/2/..-->../sup 4/I/sub 11/2/ and /sup 4/F/sub 3/2/..-->../sup 4/F/sub 9/2/ emission of Nd/sup 3 +/ in silicate laser glasses are measured using resonant and nonresonant fluorescence line narrowing techniques. The observed depolarization ratio is a measure of the anisotropy of the stimulated emission cross section and the degree of polarization hole burning that will occur for lasers operating in the large-signal gain regime.
  • Supercontinuum (SC) stimulated emission depletion (STED) fluorescence lifetime imaging is demonstrated by using time-correlated single-photon counting (TCSPC) detection. The spatial resolution of the developed STED instrument was measured by imaging monodispersed 40-nm fluorescent beads and then determining their fwhm, and was 36 ± 9 and 40 ± 10 nm in the X and Y coordinates, respectively. The same beads measured by confocal microscopy were 450 ± 50 and 430 ± 30 nm, which is larger than the diffraction limit of light due to underfilling the microscope objective. Underfilling the objective and time gating the signal were necessary to achieve themore » stated STED spatial resolution. The same fluorescence lifetime (2.0 ± 0.1 ns) was measured for the fluorescent beads by using confocal or STED lifetime imaging. The instrument has been applied to study Alexa Fluor 594-phalloidin labeled F-actin-rich projections with dimensions smaller than the diffraction limit of light in cultured cells. Fluorescence lifetimes of the actin-rich projections range from 2.2 to 2.9 ns as measured by STED lifetime imaging.« less
