... this interference. That process thus has not been observed in a roomtemperature solid-state material, which would be desirable for practical uses of slow-light methods. However, the process of coherent population oscillations also leads to very slow propagation of light pulses, and this can occur in ...

... The Fresnel equations describe how much phase is accumulated as a wave propagates through a material: T or F 1i) The reflectivity of a plane wave incident on a thin dielectric film with a fixed refractive index depends on the frequency of the lightwave: T or F 1j) When calculating the electromagneti ...

This drift will be an impediment to your measurements, and some of you will be fortunate and will have much more stable l ...

INTRODUCTION
... Light is an Electromagnetic wave. It consists wave fronts. The lines normal to the wave fronts are called the light rays. If the phase fronts are concentric spheres, the light is called a spherical wave, and if the phase fronts are parallel planes, the light is called a plane wave. For a plane waves ...

... The best resolution that can be obtained by diffractionlimited (200 nm) optical techniques is coarser than the molecular level by two orders of magnitude (2 nm). Twofold improvements in resolution (approximately 100 nm) can be obtained in either confocal (4Pi) or widefield (I5M) technologies. ...
