An open systems approach to quantum optics : lectures by Howard Carmichael

By Howard Carmichael

This quantity comprises ten lectures awarded within the sequence ULB Lectures in Nonlinear Optics on the Universite Libre de Bruxelles in the course of the interval October 28 to November four, 1991. a wide a part of the 1st six lectures is taken from fabric ready for a ebook of a little bit higher scope to be able to be published,by Springer less than the name Quantum Statistical equipment in Quantum Optics. The imperative reason behind the early booklet of the current quantity matters the fabric inside the final 4 lectures. the following i've got prepare, in a kind of systematic approach, a few principles in regards to the use of stochastic wavefunctions within the concept of open quantum optical platforms. those principles have been built with assistance from of my scholars, Murray Wolinsky and Liguang Tian, over a interval of roughly years. they're equipped on a beginning laid down in a paper written with Surendra Singh, Reeta Vyas, and Perry Rice on waiting-time distributions and wavefunction cave in in resonance fluorescence [Phys. Rev. A, 39, 1200 (1989)]. The ULB lecture notes include my first critical atte~pt to offer a whole account of the tips and their strength functions. i'm thankful to Professor Paul Mandel who, via his invitation to provide the lectures, prompted me to arrange anything precious out of labor which can, another way, have waited significantly longer to be introduced jointly.

An efficient way to generate the strong laser fields is to use ultrashort laser pulses. In principle, an unlimited temporal energy concentration can produce an unlimited electromagnetic field strength with a finite amount of input energy. With recent advances in laser technology, a tabletop laser source can readily generate an ultrashort laser pulse with a duration less than 10 fs [23, 24]. Since the spectral bandwidth and the duration of a pulse are related by the inequality ∆t∆ω ≥ 1/2, a broad bandwidth lasing material is required to generate the ultrashort laser pulses.

Schematic illustration of pole trajectories indicating the origin of LIS. 4 Possibility of Experimental Observation If we could measure photoelectron spectra in intense fields, LIS should be observed as peaks at the corresponding electron binding energy. Several authors have presented numerical simulation for the photoelectron spectra of LIS [20, 28]. In order to have sharp peaks, LIS should live sufficiently long.

Phys. Lett. edu Summary. The study of atoms and molecules in strong laser fields is one of the most active research areas in Atomic, Molecular, and Optical Physics. Following extensive study over the past two decades, most phenomena involving strong fieldatom interactions have been relatively well understood. However, there have been a number of observations suggesting that molecules in strong fields behave significantly differently from what we have learned from atoms. Revised concepts are discussed in this article for phenomena as simple as single- and double-electron ionization in molecules.
