Laser fields electrodynamics

This review is concerned with the advances in our understanding of chemical problems that have occurred as a result of developments in computational electrodynamics, with an emphasis on problems involving the optical properties of nanoscale metal particles. In addition, in part of the review we describe theoretical methods that mix classical electrodynamics with molecular quantum mechanics, and which thereby enable one to describe the optical properties of molecules that interact with nanoparticles. Our focus will be on linear optical properties, and on the interaction of electromagnetic fields with materials that are large enough in size that the size of the wavelength matters. We will not consider intense laser fields, or the interaction of fields with atoms or small molecules. [Pg.48]

As stated by Milonni [73], An arbitrarily large number n of photons may occupy the same state, and when this situation obtains, it is accurate to regard the photon wave function as defining a classical field distribution. Thus the quantum electrodynamic view of radiation for intense laser fields can be described classically. Overall, the light-matter interaction is treated semi-classically where the diatomic molecule is quantum mechanical and the laser pulse is classical in nature. The electric dipole approximation [74] is also used which reduces the form of the electric field due to the comparative size of the electric field wavelength compared to the molecule. The classical description of the laser field, E r,t), can be written in complex form according to... [Pg.264]

For nonspecialists, however, or for people who are just starting in this field, it is often difficult to find from the many articles scattered over many journals a coherent representation of the basic principles of laser spectroscopy. This textbook intends to close this gap between the advanced research papers and the representation of fundamental principles and experimental techniques. It is addressed to physicists and chemists who want to study laser spectroscopy in more detail. Students who have some knowledge of atomic and molecular physics, electrodynamics, and optics should be able to follow the presentation. [Pg.770]

As mentioned in the introduction to Parts A and B, new experimental methods have enriched and advanced the field of atomic spectroscopy to such a degree that it serves not only as a source of atomic structure data but also as a test ground for fundamental atomic theories based upon the framework of quantum mechanics and quantum electrodynamics. However, modem laser and photon correlation techniques have also been applied successfully to probe beyond the traditional quantum mechanical and quantum electrodynamical theories into nuclear stracture theories, electro-weak theories, and the growing field of local realistic theories versus quantum theories. [Pg.534]

The significance of the factor (ej /c i) in Eq. (8) was first pointed out by Csillag et al. and arises simply from taking into account carefully the electrodynamics of laser propagation in a birefringent medium. - In Eq. (8), and t are the optical dielectric constants for fields perpendicular and parallel to the director axis, respectively ... [Pg.137]

Dyson-type equations have been used extensively in quantum electrodynamics, quantum field theory, statistical mechanics, hydrodynamic instability and turbulent diffusion studies, and in investigations of electromagnetic wave propagation in a medium having a random refractive index (Tatarski, 1961). Also, this technique has recently been employed to study laser light scattering from a macromolecular solution in an electric field. [Pg.80]
