Available in PDF, EPUB and Kindle. Book excerpt: In this project we investigated four main areas: (1) Temporal shaping of picosecond laser pulses using beam coupling in a photorefractive crystal. We showed both theoretically and experimentally that one can add or subtract picosecond light pulses onto existing light pulses to create arbitrary temporal waveforms. (2) The physics of the photorefractive effect in barium titanate crystals. We showed that photovaltaic currents play an important role in the formation of photorefractive gratings in barium titanate. We also derived a theory to explain the curved beam paths observed in photorefractive phase conjugators. (3)Frequency doubling in infrared light in glass. We proved decisively that second harmonic generation in optically prepared glass is caused by a dc electric field imprisoned in the glass. We mapped the spatial profile of this dc field to a resolution of one micron. (4)Injecting diode laser arrays using phase conjugation. We demonstrated that injecting broad-area diode laser with light causes the laser array to emit a spatially and spectrally narrow output beam. We use a double phase conjugator to guide light from an injecting laser into the lasing regions of the laser array. jg.

This book was released on 2012-12-06 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonics, the counterpart of electronics, involves the usage of Photons instead of electrons to process information and perform various switching operations. Photonics is projected to be the technology of the future because of the gain in speed, processing and interconnectivity of network. Nonlinear optical processes will play the key role in photonics Where they can be used for frequency conversion, optical switching and modulation. Organic molecules and polymers have emerged as a new class of highly promising nonlinear optical materials Which has captured the attention of scientists world wide. The organic systems offer the advantage of large nonresonant nonlinearities derived from the 1T electrons contribution, femtosecond response time and the flexibility to modify their molecular structures. In addition, organic polymers can easily be fabricated in various device structures compatible with the fiber-optics communication system. The area of nonlinear optics of organic molecules and polymers offers exciting opportunities for both fundamental research and technologic development. It is truly an interdisciplinary area. This proceeding is the outcome of the first NATO Advanced Research WOrkshop in this highly important area. The objective of the workshop was to provide a forum for scientists of varying background from both universities and industries to come together and interface their expertize. The scope of the workshop was multidisciplinary with active participations from Chemists, physicists, engineers and materials scientists from many countries.

Download or read book Ultrashort Laser Pulses and Applications written by Wolfgang Kaiser and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten years ago, Stanley L. Shapiro edited the book entitled Ultrashort Light Pulses (Topics Appl. Phys., Vol. 18), which was written by eight experts in the field. Six years later, Charles V. Shank added a bibliography (1980-1983) in the second edition with approximately one thousand new references. During the past decade the field has grown so rapidly that a completely new book had to be written. In particular, the reduction of the time scale of light pulses into the femtosecond range has opened up new experimental possibilities never even foreseen in the preceding literature. The vast literature with countless ideas and applications makes it impossible for a single person to write a comprehensive review. Nine scientists, actively working in the field since its beginning, have decided to join forces to prepare a new book describing the present state of the art. Emphasis is placed on the generation and numerous applications of ultrashort laser pulses. This book covers a wide area of science: physics, engineering, chemistry, and biology. The various chapters and sections are prepared in each case such that the reader is given a brief introduction to the specific subject. Ample references for a more detailed study are given at the end of each chapter.

Download or read book Nonlinear Photonics written by Hyatt M. Gibbs and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear photonics is the name given to the use of nonlinear optical devices for the generation, communication, processing, or analysis of information. This book is a progress report on research into practical applications of such devices. At present, modulation, switching, routing, decision-making, and detection in photonic systems are all done with electronics and linear optoelectronic devices. However, this may soon change, as nonlinear optical devices, e.g. picosecond samplers and switches, begin to complement optoelectonic devices. The authors succinctly summarize past accomplishments in this field and point to hopes for the future, making this an ideal book for newcomers or seasoned researchers wanting to design and perfect nonlinear optical devices and to identify applications in photonic systems.

Book excerpt: High Excitation and Short Pulse Phenomena contains the proceeding of the Third Trieste ICTP-IUPAP Semiconductor Symposium on ""High Excitation and Short Pulse Phenomena"", held at the International Center for Theoretical Physics, Trieste, Italy on July, 2-6 1984. This book contains the keynote papers of the symposium and the contributions from the participants. It describes the non-equilibrium electron-hole plasmas in direct and indirect gap semiconductors; transport of plasmas and of hot carriers; and expansion velocities. The book also elucidates the screening effects involved in the exciton-plasma transition; the optical bistability and nonlinearity; and experimental techniques with short pulse spectroscopy. Other topics emphasized are the physical aspects of laser annealing and of melting at the highest excitation levels, as well as the results of high excitation and short pulse physics of quantum wells. The fast relaxation processes, as well as the carrier-carrier and carrier-phonon interactions are also explained. This material will serve as a source of information and reference, and will stimulate ways for further research.
