    ABSTRACT: We report a versatile setup based on the femtosecond adaptive spectroscopic techniques for coherent anti-Stokes Raman scattering. The setup uses a femtosecond Ti:Sapphire oscillator source and a folded 4f pulse shaper, in which the pulse shaping is carried out through conventional optical elements and does not require a spatial light modulator. Our setup is simple in alignment, and can be easily switched between the collinear single-beam and the noncollinear two-beam configurations. We demonstrate the capability for investigating both transparent and highly scattering samples by detecting transmitted and reflected signals, respectively.

    ABSTRACT: We present a unique confocal microscope capable of measuring the Raman and Brillouin spectra simultaneously from a single spatial location. Raman and Brillouin scattering offer complementary information about a material's chemical and mechanical structure, re-spectively, and concurrent monitoring of both of these spectra would set a new standard for material characterization. We achieve this by applying recent innovations in Brillouin spectroscopy that reduce the necessary acquisition times to durations comparable to conventional Raman spectroscopy while attaining a high level of spectral accuracy. To demonstrate the potential of the system, we map the Raman and Brillouin spectra of a molded PEGDA hydrogel sample in cyclohexane to create two-dimensional images with high contrast at microscale resolutions. This powerful tool has the potential for very diverse analytical applications in basic science, industry, and medicine.

    ABSTRACT: Interaction of atoms with quantum states of light is a long-standing problem that apart from fundamental physics has potential applications for optical quantum-state storage, quantum communication, and quantum information. A fully quantum mechanical treatment of this problem is usually very complicated mathematically. Here we show, however, that quantum mechanical evolution equations describing single-photon emission (absorption) by atomic ensembles can be written in a form equivalent to the semiclassical Maxwell-Bloch equations. This connection allows us to find exact analytical solutions of the fully quantum mechanical problem. We also found that semiclassical Maxwell-Bloch equations should be written in a form different from those commonly used. Namely, the classical limit of the quantum problem gives a propagation equation with the Laplacian operator on the right-hand side rather than with the second-order time derivative.

    ABSTRACT: Currently, no light source exists which is both narrow-band and speckle-free with sufficient brightness for full-field imaging applications. Light emitting diodes (LEDs) are excellent spatially incoherent sources, but are tens of nanometers broad. Lasers on the other hand can produce very narrow-band light, but suffer from high spatial coherence which leads to speckle patterns which distort the image. Here we propose the use of random Raman laser emission as a new kind of light source capable of providing short-pulsed narrow-band speckle-free illumination for imaging applications.

    ABSTRACT: Monte Carlo techniques are the gold standard for studying light propagation in turbid media. Traditional Monte Carlo techniques are unable to include wave effects, such as diffraction; thus, these methods are unsuitable for exploring focusing geometries where a significant ballistic component remains at the focal plane. Here, a method is presented for accurately simulating photon propagation at the focal plane, in the context of a traditional Monte Carlo simulation. This is accomplished by propagating ballistic photons along trajectories predicted by Gaussian optics until they undergo an initial scattering event, after which, they are propagated through the medium by a traditional Monte Carlo technique. Solving a known problem by building upon an existing Monte Carlo implementation allows this method to be easily implemented in a wide variety of existing Monte Carlo simulations, greatly improving the accuracy of those models for studying dynamics in a focusing geometry.

    ABSTRACT: We demonstrate an approach to detect low wavenumber vibrational signals based on single-beam coherent anti-Stokes Raman scattering (CARS) with a spectral hole.

    ABSTRACT: Spatially Offset Raman Spectroscopy (SORS) has seen considerable interest in recent years as a tool for noninvasively acquiring Raman spectra from beneath the surface of a sample. One of the major limitations of the SORS technique is that accurate knowledge of the optical properties of the medium is required to translate an offset into a sample depth. We report on the benefits of preforming SORS using micron offset distances as opposed to the more typical millimeter offsets used. Monte Carlo simulations are used to demonstrate that at these small offsets, the results depend less on the scattering coefficient of the material. These results provide new insights into the SORS technique and will improve the practical application of SORS in the future.

    ABSTRACT: Monte Carlo methods have become the gold standard for investigating the properties of light transport in turbid media due to their simple conceptual picture and quantitative agreement with experiment. However, these approaches are limited to the study of linear effects. In this work, a model capable of efficiently and accurately simulating stimulated Raman scattering in a turbid environment is presented for the first time. The method is validated using both analytical calculations and experimental data. These results will allow for a deeper understanding of nonlinear light propagation in a turbid medium and will be indispensable in understanding the processes involved in random Raman lasing.Keywords: Monte Carlo; stimulated Raman scattering; turbid media; random Raman lasing

    ABSTRACT: We demonstrate a scanning fiber-optic probe for magnetic-field imaging where nitrogen-vacancy (NV) centers are coupled to an optical fiber integrated with a two-wire microwave transmission line. The electron spin of NV centers in a diamond microcrystal attached to the tip of the fiber probe is manipulated by a frequency-modulated microwave field and is initialized by laser radiation transmitted through the optical tract of the fiber probe. The two-dimensional profile of the magnetic field is imaged with a high speed and high sensitivity using the photoluminescence spin-readout return from NV centers, captured and delivered by the same optical fiber.

    ABSTRACT: Amplified ultrashort laser pulses are useful in many fields of science and engineering. Pushing the frontiers of ultrashort pulse generation will lead to new applications in biomedical imaging, communications and sensing. We propose a new, quantum approach to ultrashort pulse generation using transient quantum coherence which predicts order of magnitude stronger pulses generated with lower input energy than in the steady-state regime, reducing the practical heating limitations. This femtosecond quantum-coherent analog of nanosecond Q-switching is not limited by the pulse duration constraints of the latter, and, in principle, may be used for a variety of lasers including x-ray and plasmon nanolasers. We apply this approach to generation of giant plasmon pulses and achieve quantum control of plasmon relaxation dynamics by varying the drive pulse delay, amplitude and duration. We provide insights into the control mechanisms, and discuss future implementations and applications of this new source of ultrashort nanooptical fields.

    ABSTRACT: Spasers have been theoretically predicted and experimentally observed and promise to deliver new exciting nanophotonic and biomedical applications. Here we theoretically investigate ultrafast dynamical properties of spasers with external plasmonic feedback. We consider a spaser both as a nanoscale source and detector of plasmons which could be used to design novel nano-imaging and sensing techniques. We show that, as with conventional lasers, spasers are sensitive to external feedback. However, unlike the lasers, spasers have faster relaxation dynamics which could be used to develop new ultrasensitive near field imaging techniques. We investigate the dependence of spaser relaxation oscillations on feedback parameters and show that quantum coherence can be used to increase the sensitivity to feedback.

    ABSTRACT: We study backward cooperative emissions from a dense sodium atomic vapor. Ultrashort pulses produced from a conventional amplified femtosecond laser system with an optical parametric amplifier are used to excite sodium atoms resonantly on the two-photon 3S–4S transition. Backward superfluorescent emissions (BSFEs), both on the 4S–3P and 4S–3P transitions, are observed. The picosecond temporal characteristics of the BSFE are observed using an ultrafast streak camera. The power laws for the dependencies of the average time delay and the intensity of the BSFEs on input power are analyzed in the sense of cooperative emission from nonidentical atomic species. As a result, an absolute (rather than relative) time delay and its fluctuations (free of any possible external noise) are determined experimentally. The possibility of a backward swept-gain superfluorescence as an artificial laser guide star in the sodium layer in the mesosphere is also discussed.

    ABSTRACT: Peaks, dips, and intermediate line shapes have been observed in surface-enhanced coherent Raman spectroscopy. Here, we report an experimental observation of a peculiar line shape revealing both a peak and a dip as two vibrational transitions of pyridazine in the presence of aggregated gold nanoparticles. We propose a simple model based on plasmonic phase effects and quantum chemistry calculations, and compare the simulated coherent (SECARS) and incoherent (SERS) Raman signals from several complexes. Complex SECARS line shapes provide additional information compared to SERS and can be used as a tool in nanoscale sensing and spectroscopy.

    ABSTRACT: We discuss a class of quantum memory (QM) scheme based on phase matching control (PMC). A single-photon wave packet can be mapped into and retrieved on demand from a long-lived spin grating in the presence of a control field, forming along with the signal field a Raman configuration, when the wave vector of the control field is continuously changed in time. Such mapping and retrieval takes place due to the phase matching condition and requires neither a variation of the amplitude of the control field nor inhomogeneous broadening of the medium. We discuss the general model of PMC QM and its specific implementation via (i) modulation of the refractive index, (ii) angular scanning of the control field, and (iii) its frequency chirp. We show that the performance of the PMC QM protocol may be as good as those realized in the gradient echo memory (GEM) but achieved with less stringent requirements on the medium. We suggest the experimental realization of PMC QM in nitrogen vacancies (NV) and silicon vacancies (SiV) in diamond as well as in rare-earth doped crystals.
