Nonlinear Diffuse fs-Pulse Reflectometry of Harmonic Upconversion Nanoparticles

Nonlinear diffuse femtosecond-pulse reflectometry is introduced as a powerful experimental tool for the unambiguous characterization of polar and non-polar point symmetry groups of harmonic upconversion nanoparticles. Using intense ultrashort 40 femtosecond laser pulses and an appropriate figure of merit (FOM), second and third harmonic emission serve for the structural characterization of polar Yb-doped lithium niobate and non-polar titanium dioxide nanoparticles. The tool is capable of differentiating these two samples by FOM values that differ by up to 13 orders of magnitude. The general applicability to harmonic upconversion nanoparticles over a broad range of intensities and wavelength spectrum, is discussed.

“…The absolute value of χ (2) was evaluated by comparing the SHG signal with that from quartz (0.6 pm/V) [57]. The SHG results were very weak: (1.04 ± 0.06) × 10 −3 pm/V for the s-s polarization and (1.44 ± 0.41) × 10 −3 pm/V for the p-p polarization.…”

Experimental and Theoretical Studies of the Second-and Third-Order NLO Properties of a semi-organic compound: 6-Aminoquinolinium Iodide Monohydrate, Chemical Physics (2013), doi: http:// dx.doi.org/10. 1016/j.chemphys.2013.11.001 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. AbstractA new semi-organic compound, 6-aminoquinolinium iodide monohydrate (I), has been synthesized and characterized by single crystal X-ray diffraction, UV-Vis absorption and fluorescence spectroscopy and nonlinear optical (NLO) measurements. The second-and third-order NLO responses were investigated with the second-and third-harmonic Maker fringes techniques, carried out on thin films at a fundamental wavelength of 1064 nm. From the molecular structure, the molecular hyperpolarizability tensors were determined with density functional theory and second-order Møller-Plesset perturbation method. The second-and third-order susceptibility tensors of the reported crystal were evaluated using the oriented gas model with the Lorenz-Lorentz and the Wortmann-Bishop local-field corrections. The calculations using the Wortmann-Bishop local-field were able to reproduce the correct order of magnitude of the experimental third-order susceptibilities. The value of χobtained by summing the effective third-order polarizability calculated for the asymmetric unit surrounded by ESP-derived charges have also the same order of magnitude of the experimental.

“…However, a relative contribution of the two processes could be different. In some cases, the direct THG process is stronger (see, e.g., Feve, Boulanger, and Guillien [2000]), in other cases the cascading THG process is dominant (see, e.g., Banks, Feit, and Perry [2002]; Bosshard, Gubler, Kaatz, Mazerant, and Meier [2000]). …”

“…In the early days of nonlinear optics, the motivation to study this kind of parametric interactions was to explore various possibilities for the simultaneous generation of several harmonics in a single nonlinear crystal (see, e.g., Akhmanov and Khokhlov [1964,1972]) as well as to use the cascading of several parametric processes for measuring higher-order susceptibilities in nonlinear optical crystals (see, e.g., Yablonovitch, Flytzanis, and Bloembergen [1972]; Akhmanov, Dubovik, Saltiel, Tomov, and Tunkin [1974]; Akhmanov [1977]; Kildal and Iseler [1979]; Bloembergen [1982]). More recently, these processes were proved to be efficient for the higher-order harmonic generation, for building reliable standards for the third-order nonlinear susceptibility measurements (see, e.g., Bosshard, Gubler, Kaatz, Mazerant, and Meier [2000] and references therein), and also for generating multi-color optical solitons. Additionally, it is expected that the multistep parametric processes and multistep cascading will find their applications in optical communication devices, for wavelength shifting and all-optical switching (see discussions below).…”

We present a comprehensive overview of different types of parametric interactions in nonlinear optics which are associated with simultaneous phase-matching of several optical processes in quadratic nonlinear media, the so-called multistep parametric interactions. We discuss a number of possibilities of double and multiple phase-matching in engineered structures with the sign-varying second-order nonlinear susceptibility, including (i) uniform and non-uniform quasi-phase-matched (QPM) periodic optical superlattices, (ii) phase-reversed and periodically chirped QPM structures, and (iii) uniform QPM structures in non-collinear geometry, including recently fabricated two-dimensional nonlinear quadratic photonic crystals. We also summarize the most important experimental results on the multi-frequency generation due to multistep parametric processes, and overview the physics and basic properties of multi-color optical parametric solitons generated by these parametric interactions.
