Available in PDF, EPUB and Kindle. Book excerpt: Whenever a circularly polarized laser beam propagates along an axis of three-fold symmetry in a piezoelectric crystal, the second harmonic polarization is circularly polarized in the opposite sense. Rabin and Bey have discussed the theory of second harmonic generation in crystals with natural optical activity. We have observed this circular polarization and also the difference in coherence lengths for opposite senses of circular polarization, with both fundamental and second harmonic beams propagating along the (111) direction in single crystals of NaClO3 and NaBrO3, belonging to the cubic class 23, for which the proper eigenmodes are circularly polarized waves. The nonlinear susceptibility of both NaClO3 and NaBrO3 has been measured and compared with the nonlinear susceptibility of a-quartz. The relative sign of the susceptibilities has been determined in second harmonic interference experiments with the same laser beam traversing two crystals in succession. The interesting question of the sign of the nonlinear susceptibility, piezoelectric constant, optical activity, and the absolute atomic configuration of the antipodes is discussed. The question of conservation of angular momentum is resolved by taking into account the crystalline field potential of three-fold symmetry which gives rise to a torque on the crystal lattice.

This book was released on 2018 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The PhD project, entitled "Second harmonic generation in disordered nonlinear crystals: application to ultra-short laser pulse characterization", is devoted to the study of second harmonic generation in nonlinear ferroelectric crystals formed by a random distribution of domains with inverted quadratic nonlinear susceptibility (such as the Strontium Barium Niobate and Calcium Barium Niobate crystals) and its application to the single-shot characterization of ultrashort laser pulses. The basic principle of operation is related to the unique type of emission associated to those kinds of crystals where the second harmonic signal is emitted transversally to the beam propagation direction. Using the transverse second harmonic generation from these crystals we measure the pulse duration, the chirp parameter and the temporal profile in a single-shot configuration. This method has been implemented both in transverse auto-correlation and transverse cross-correlation schemes for the measurement of pulses with durations in the range from several tens up to several hundreds of femtoseconds. The main advantages gained with the developed techniques against other traditional methods include the removal of the requirement of thin nonlinear crystals for harmonic generation, the possibility to get automatic phase matching without angular alignment or temperature control over a very wide spectrum and a simplified operation process. Different types of pulses have been measured in different conditions and the limits of validity of the technique have been explored. Since this work relies strongly upon the characteristics of emission of the second harmonic signal by these random crystals, an important part of this work has been focused on the characterization of the distribution of domains of the random nonlinear ferroelectric crystals and its relation with the angular emission of the second harmonic signal. The domain distribution of the nonlinear polarization implies an associated distribution of reciprocal lattice vectors, which can compensate the phase mismatch in the nonlinear interaction. Any change in the domain distribution would have a direct impact in the second harmonic generated and in its intensity angular distribution. Based on these fundamental concepts we demonstrate an indirect non-destructive optical method for the characterization of nonlinear domain statistics based on the analysis of the second harmonic generation intensity angular distribution. This method has been implemented experimentally and tested in crystals with different types of distributions. To gain a deeper insight on these processes, numerical simulations have been performed using a split-step fast-Fourier transform beam propagation method. It has been demonstrated that the analysis of the dependence of the second harmonic generation angular emission with the fundamental beam wavelength can be used to obtain relevant information about complicated domain structures. This method could be used for real time monitoring of the unknown domain distribution during the poling or crystal growing process.

Available in PDF, EPUB and Kindle. Book excerpt: This book is mostly concerned on the experimental research of the nonlinear optical characteristics of various media, low- and high-order harmonic generation in different materials, and formation, and nonlinear optical characterization of clusters. We also demonstrate the inter-connection between these areas of nonlinear optics. Nonlinear optical properties of media such as optical limiting can be applied in various areas of science and technology. To define suitable materials for these applications, one has to carefully analyse the nonlinear optical characteristics of various media, such as the nonlinear refractive indices, coefficients of nonlinear absorption, saturation absorption intensities, etc. Knowing the nonlinear optical parameters of materials is also important for describing the propagation effects, self-interaction of intense laser pulses, and optimisation of various nonlinear optical processes. Among those processes one can admit the importance of the studies of the frequency conversion of coherent laser sources. The area of interest for nonlinear optical characterization of materials is also closely related with new field of nanostructures formation and application during laser-matter interaction. We show how the nonlinear optical analysis of materials leads to improvement of their high-order nonlinear optical response during the interaction with strong laser fields. Ablation-induced nanoparticles formation is correlated with their applications as efficient sources of coherent short-wavelength photons. From other side, recent achievements of harmonic generation in plasmas are closely related with the knowledge of the properties of materials in the laser plumes. All of these studies are concerned with the low-order nonlinear optical features of various materials. The novelty of the approach developed in present book is related with inter-connection of those studies with each other.

Available in PDF, EPUB and Kindle. Book excerpt: Research on ferroelectricity and ferroelectric materials started in 1920 with the discovery by Valasek that the variation of spontaneous polarization in Rochelle salt with sign and magnitude of an applied electric field traced a complete and reproducible hysteresis loop. Activity in the field was sporadic until 1935, when Busch and co-workers announced the observation of similar behavior in potassium dihydrogen phosphate and related compounds. Progress thereafter continued at a modest level with the undertaking of some theoretical as well as further experimental studies. In 1944, von Hippel and co-workers discovered ferroelectricity in barium titanate. The technological importance of ceramic barium titanate and other perovskites led to an upsurge of interest, with many new ferroelectrics being identified in the following decade. By 1967, about 2000 papers on various aspects of ferroelectricity had been published. The bulk of this widely dispersed literature was concerned with the experimental measurement of dielectric, crystallographic, thermal, electromechanical, elastic, optical, and magnetic properties. A critical and excellently organized cpmpilation based on these data appeared in 1969 with the publica tion of Landolt-Bornstein, Volume 111/3. This superb tabulation gave instant access to the results in the literature on nearly 450 pure substances and solid solutions of ferroelectric and antiferroelectric materials. Continuing interest in ferroelectrics, spurred by the growing importance of electrooptic crystals, resulted in the publication of almost as many additional papers by the end of 1969 as had been surveyed in Landolt-Bornstein.
