Propagation of light in a J = 1 / 2 - J = l / 2 resonant medium
نویسنده
چکیده
The propagation of light in a resonant medium with multiple sublevels depends on the populations of and coherences between theses sublevels. We analyze the case of a J= 1/2-J = l/2 transition with arbitrary ground-state polarization in the limit of a weak probe beam. It is found that transverse components of the ground-state orientation lead to a longitudinal component in the eigenpolarizations; a laser beam propagating through an optically pumped medium should therefore be displaced laterally.

Application of Embryo Rescue Technique in Juglans regia L. x J. nigra L. Hybridization
Embryo culture were used to produce inter specific walnut hybrid plants between Juglans nigra L. and J. regia L. Developed ovaries were collected from J. rejia female flowers which were pollinated with J. nigra pollen grain by high dusting on a mature tree. In order to isolate embryos, exocarps were aseptically removed. Isolated embryos from ovules at different developmental stages were transfe...

Petunia (Petunia hybrida) is an ornamental plant species of high economic potential. One of the appropriate methods for propagation and breeding of petunia is tissue culture. This experiment was conducted to investigate the effects of different concentrations of benzyl adenine (BA) either alone or in combination with different concentrations of naphthalene acetic acid (NAA) on the regeneration ...

Micro-propagation of olive provides the possibility of producing clones of native plants with appropriate attributes and mass reproduction in short period of time, compared to conventional methods. Apical dominance in olive explants limits the growth of lateral branches in vitro. The effect of Woody Plant Medium (WPM), Olive Medium (OM) and Murashig and Skoog (MS) with carbohydrate source (mann...
متن کاملQuantum Squeezed Light Propagation in an Optical Parity-Time (PT)-Symmetric Structure
We investigate the medium effect of a parity-time (PT)-symmetric bilayer on the quantum optical properties of an incident squeezed light at zero temperature (T=0 K). To do so, we use the canonical quantization approach and describe the amplification and dissipation properties of the constituent layers of the bilayer structure by Lorentz model to analyze the quadrature squeezing of the outgoing ...
متن کاملEffective Medium Theory for Acoustic Waves in Bubbly Fluids near Minnaert Resonant Frequency
We derive an effective medium theory for acoustic wave propagation in bubbly fluid near Minnaert resonant frequency. We start with a multiple scattering formulation of the scattering problem of an incident wave by a large number of identical small bubbles in a homogeneous fluid. Under certain conditions on the configuration of the bubbles, we justify the point interaction approximation and esta...
