Although many materials are capable of generating laser light, few operate at the shorter wavelengths. Scientists from the Fraunhofer Institute have a laser that produces wavelengths of down to 370[mu], near UV range, achieved by a frequency-doubling technique. Andreas Hofmann leads the IPM's ...

The biologically effective UV radiation is obtained by integrating the biologically effective spectral irradiance over the whole wavelength range. Biotic: A biotic factor is a feature or process derived from, or caused by, living organisms, which might affect other living organisms in their environment...

Of particular consequence to the scattering/absorption of light is the surface plasmon resonance (SPR); a collective oscillation of the conduction electrons induced by a passing electromagnetic field. The nanoparticle size, shape, orientation and permittivity determine the frequency of this SPR. Alloy ...
The frequency of spontaneous mutation formation in sham-irradiated cells was low, with 0.3±0.6 mutants/one million colony-forming cells (mean±standard deviation; n=5). Increasing mutation frequencies were observed with increasing doses of UVA or UVB (Figure 1). With 200 kJ/m2 UVA, the induc...
It reveals spectrally well separated optical absorption features in the visible and near-infrared spectral range, their small polaron peak energies and lineshapes. Nonlinear interaction of light is assigned to the optical formation of short-lived small polarons as a result of carrier excitation by ...
