The Laser Driven Vacuum Photodiode

A vacuum photodiode is constructed in the form of a parallel plate capacitor with plate separation d. A battery maintains constant potential V between the plates. A short laser pulse illuminates that cathode at time t = 0 with energy sufficient to liberate all of the surface charge density. This charge moves across the capacitor gap as a sheet until it is collected at the anode at time T . Then...

Sonoluminescence as quantum vacuum radiation.

Sonoluminescence is explained in terms of quantum radiation by moving interfaces between media of different polarizability. It can be considered as a dynamic Casimir effect, in the sense that it is a consequence of the imbalance of the zero-point fluctuations of the electromagnetic field during the non-inertial motion of a boundary. The transition amplitude from the vacuum into a two-photon sta...

UV radiation and the Eye

It has been said that aside from skin, the organ most susceptible to sunlight-induced damage is the eye. In view of this, it can be argued that the optical industry and the eye care professional have an obligation, or at least, an opportunity, to educate the public more widely on the dangers of ocular exposure to UV and how best to achieve protection. This article summarises our understanding o...

UV-radiation, apoptosis and skin.

Apoptosis or programmed cell death is a key function in regulating skin development, homeostasis and tumorigenesis. The epidermis is exposed to various external stimuli and one of the most important is UV radiation. The UVA and UVB spectra differ in their biological effects and in their depth of penetration through the skin layers. UVB rays are absorbed directly by DNA which results in its dama...
