Persistent spectral hole-burning : science and application by W. E Moerner( Book )

9 editions published in 1988 in English and German and held by 194 WorldCat member libraries worldwide

This book describes the underlying scientific fundamentals and principal phenomena associated with persistent spectral hole-burning in solids, and presents an overview of possible future applications to optical storage of digital data and optical signal processing. Organization of the material is by the general physical mechanism responsible for the formation of persistent spectral holes. After a description of the basic principles and methods of hole-burning, with examples from photochemical processes in crystalline and amorphous hosts, the unusual proton tunneling phenomena that occur in hydrogen-bonded polymers and glasses are described. Persistent spectral hole-burning in inorganic materials due either to photoionization or to photophysical effects is then summarized, followed by a detailed discussion of nonphotochemical hole-burning mechanisms for electronic transitions in amorphous solids. The book concludes with a description of potential applications to data storage and optical processsing using frequency-domain, holographic, and electric field techniques. Readers of this volume will gain a detailed appreciation of both the generality of the persistent spectral hole-burning phenomenon and the power of the technique in studying microscopic dynamics and mechanisms of phototransformation in low-temperature solids

Frequency Domain Optical Storage by G. C Bjorklund( Book )

2 editions published between 1981 and 1982 in Undetermined and English and held by 2 WorldCat member libraries worldwide

The phenomenon of photochemical hole burning makes it possible to utilize optical frequency as an additional dimension for the organization of an optical data store. Storage densities of 10 to the 11th power bits/cm squared may ultimately be achieved. The basic principles of photochemical hole burning are reviewed in this paper and recent research results are presented. (Author)
Research Studies on Nonlinear Optical Processes in Metallic Vapors( Book )

1 edition published in 1972 in English and held by 1 WorldCat member library worldwide

Described is research work aimed at the development of techniques for frequency tripling laser radiation which is incident on mixtures of metal vapors and inert gases. Principal accomplishments of the program include: the demonstration of the first nonlinear optical technique in the vacuum ultraviolet region of the spectrum; the generation of kW peak powers at 1773 A, 1520 A, and 1182 A; the development of a very general analysis for studying the potential conversion efficiency in the alkali metal-inert gas system; and most recently the proposal and demonstration of the very simple technique of third harmonic generation in mixtures of inert gases.

Persistent Spectral Hole-Burning for R' Color Centers in LiF Crystals. Statics, Dynamics, and External Field Effects( Book )

1 edition published in 1985 in English and held by 1 WorldCat member library worldwide

The persistent spectral hoe-burning properties of R' color centers in pure and doped LiF single crystals at liquid helium temperatures are described and analyzed. Using FM spectroscopy and precision ratiometric transmission spectroscopy, a satellite hole structure has been observed which varies with position in the inhomogeneous line due to excited state splittings. Transient effects in the optical absorption indicate that an intermediate state with millisecond lifetimes is involved in hole formation. The persistent holes have been observed to grow as the logarithm of time and the logarithm of burning intensity in certain regimes, and a phenomenological tunnelling model has been used to explain the time and intensity dependence. The results suggest that R' centers interact via tunneling and local strains with a quasi-random distribution of nearby traps which may be other color centers in the host material. A linear Stark effect has been observed in agreement with earlier measurements. The power of hole-burning spectroscopy to uncover static and dynamic interactions normally hidden by inhomogeneous broadening is illustrated
Symposium on Polymeric Materials for Photonic and Optical Applications Held in New York, NY on August 25-30, 1991( )

1 edition published in 1992 in English and held by 1 WorldCat member library worldwide

A symposium on Polymeric Materials for Photonic and Optical Applications was held as part of the 4th Chemical Congress of North America and 202nd ACS National Meeting during August 25-30, 1991 in New York, N.Y. This symposium was sponsored by the ACS Division of Polymer Chemistry and the ACS division of Polymeric Materials: Science and Technology with the cooperation of the Optical Society of America. The symposium organizers were G.C. Bjorklund, G. Hadziioannou, J. Torkelson, and M.A. Winnik. The goal of the symposium was to cover in depth the chemistry, characterization, and device application of polymers for photonics and optics. The major objective was to bring together leading experts from around the world to elucidate the major scientific challenges and hurdles that must be overcome for photonic polymers to reach their full potential and find major device applications. The symposium consisted of a tutorial session, a poster session, and five oral sessions, extending over three full days. A total of 32 distinguished scientists presented invited papers. Of these, 21 were from North America, 9 from Europe, and 2 from Japan. In addition, 28 contributed papers were presented. Interactions among the attendees were quite good and the overall attendance was strong, with some of the sessions being held by more than 250 people

Reading and Writing of Photochemical Holes Using GaA1As Diode Lasers( Book )

1 edition published in 1983 in English and held by 1 WorldCat member library worldwide

A current tuned (gallium aluminum arsenide) diode laser is utilized both to burn and to detect narrow photochemical holes in the inhomogeneously broadened 833 nm zero phonon line of the R' color center in LiF. Applications for reading and writing data into frequency domain optical memories based on photochemical hole burning are discussed. (Author)
Frequency Domain Optical Storage and Other Applications of Persistent Spectral Hole-Burning( Book )

1 edition published in 1987 in English and held by 1 WorldCat member library worldwide

The previous chapters have described the fundamental physical and chemical changes that can lead to the formation of persistent spectral holes in inhomogeneously broadened optical or infrared transitions in solids at low temperatures. Persistent spectral hole-burning (PSHB) has proven to be a powerful tool for high-resolution spectroscopy of impurities in solids that can be used to study dephasing mechanisms, microenvironments in crystals, amorphous host dynamics, low-temperature solid-state photochemistry, and microscopic perturbations due to external fields. At the same time, PSHB has the potential for technological applications to optical data storage, pulse shaping, and optical signal processing. This has resulted in engineering and materials research on PSHB at a variety of laboratories around the world. In this chapter, several potential technological applications of persistent spectral hole-burning will be reviewed. The application that has received the most attention so far is based on the concept of using persistent spectral hole-burning to form a frequency domain optical storage (FDOS) system. In FDOS, the optical freqeuency or wavelength at which holes are burned is used to encode digital information where, for instance, the presence of a hole at a particular optical frequency may be used to encode a digital 1 and the absence of a hole a digital 0

Investigations of Photochemistry Using Holography and Photoacoustic Spectroscopy( Book )

1 edition published in 1984 in English and held by 1 WorldCat member library worldwide

The work supported by this contract had as its primary goal the development of a holographic technique for the investigation of the details of photochemical reactions. The technique involves imbedding a molecule whose photochemistry we wish to study into a polymer or other host material. By exposing this system to the radiation from interfering laser beams one can produce a hologram in the material, By following the growth in scattering efficiency of the hologram as a function of time, one can study the underlying photochemistry producing the holographic technique is particularly useful in investigating two-photon photochemical process, i.e., processes that require the stepwise absorption of two photons
