This book was released on 1998 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work we experimentally investigate a singly resonant optical parametric oscillator (OPO) with an intracavity crystal that mixes the signal and idler waves, enhancing the power conversion efficiency of the idler radiation. Optical parametric oscillators provide a method for producing coherent tunable radiation from a coherent fixed-frequency pump source. The pump frequency Wp 15 converted to the signal and idler frequencies Ws and Wi, respectively, in the OPO interaction, Wp = Ws + Wi, Ws> Wi. Since the signal and idler frequencies sum to the incident pump frequency, they are always lower than the pump frequency. Extra-cavity difference-frequency mixing (DFM) of the signal and idler from an OPO was demonstrated in some early experiments and recently a number of investigators have examined mixing the signal and idler waves generated from a synchronously pumped OPO to produce long-wavelength difference-frequency radiation. Here the difference-frequency Wd is produced in the DFM interaction, Wd = Ws - Wi. The DFM process not only produces long-wavelength radiation at the difference frequency, but for each difference-frequency photon produced, another idler photon is produced. Thus, this technique also increases the idler-frequency conversion efficiency. Production of the long-wavelength difference-frequency photons may not be possible in a single-step OPO process, due to transmission bands and phase-matching limitations of available crystals and available pump wavelengths.
Download or read book Continuous Wave 4 3 mu Intracavity Difference Frequency Generation in an Optical Parametric Oscillator written by and published by . This book was released on 2001 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have achieved 150 mW of cw output at 4.3 micrometers, using difference frequency mixing in a singly resonant optical parametric oscillator (OPO). We pumped the OPO cavity, which contains periodically poled LiNbO3 (PPLN), with a 14-W 1.06-micrometers Nd:YAG laser to generate a signal at 1.7 micrometers and an idler at 2.8 micrometers. Mixing of the two waves at the same crystal temperature and grating spacing yielded emission in the mid IR. This technique avoids the mid-IR absorption-high-threshold problem, which has limited the cw performance of PPLN OPOs at wavelengths beyond 4 micrometers. Provided that tunability is not required, this method is a simple alternative to multiple-crystal configurations.

Download or read book Tunable Synchronously Pumped Intracavity Two Stage Optical Frequency Upconversion written by and published by . This book was released on 1993 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical parametric oscillation (OPO) with intracavity sum-frequency generation (SFG) of the signal and pump has been studied theoretically and numerically, using the CW plane wave theory as well as a numerical code developed to simulate either synchronously pumped pulse propagation or walk-off effects in one transverse dimension. The configuration where the SFG crystal precedes the OPO crystal in the cavity gives stable high-efficiency conversion over a larger range of pump intensity, as well as lower power loading on the OPO crystal. About 85 percent conversion efficiency from 1.064 microns to 589 nm is predicted at pump intensities up to 9 MW/sq cm for a device using AgGaS2 and KTP crystals. Also, the angular distribution of parametric fluorescence from AgGaS2 has been calculated in good agreement with measurements made at the Phillips Laboratory.
Download or read book Ion Exchange in Single Crystals for Integrated Optics and Optoelectronics written by Yu N. Korkishko and published by Cambridge Int Science Publishing. This book was released on 1999 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book addresses many problems of ion exchange processes in LiNbO3, LiTaO3 and KTiOPO4 ferroelectrics and II-VI semiconductor single crystals for integrated optics applications. The authors start with the fundamentals of ion exchange processes in solids (Chapter 1). Chapter 1 can be considered also as an enlarged introduction to the book. Starting with Chapter 2, the general properties of LiNbO3 and LiTaO3 crystals, the methods used to study optical waveguides in these crystals as well as advanced preparation methods of optical waveguides are reviewed. Chapters 3, 4 and 5 are devoted to recent progress in the ion exchange processes in LiNbO3, LiTaO3 and KTiOPO4 crystals, respectively, and Chapter 6 summarizes the main applications of ion-exchanged waveguides in modern integrated optics. Finally, Chapter 7 deals with recently established ion exchange processes in II-VI semiconductors.

It covers applications through detailed case studies, and is therefore well suited to readers who wish to use it to solve specific problems of their own. The first of the three volumes comprises an introduction to the basic scientific principles of lasers, laser beams and non-linear optics. The second volume describes the mechanisms and operating characteristics of specific types of laser including crystalline solid - state lasers, semiconductor diode lasers, fibre lasers, gas lasers, chemical lasers, dye lasers and many others as well as detailing the optical and electronic components which tailor the laser's performance and beam delivery systems. The third volume is devoted to case studies of applications in a wide range of subjects including materials processing, optical measurement techniques, medicine, telecommunications, data storage, spectroscopy, earth sciences and astronomy, and plasma fusion research. This vast compendium of knowledge on laser science and technology is the work of over 130 international experts, many of whom are recognised as the world leaders in their respective fields. Whether the reader is engaged in the science, technology, industrial or medical applications of lasers or is researching the subject as a manager or investor in technical enterprises they cannot fail to be informed and enlightened by the wide range of information the Handbook supplies.
