Nonlinear propagation of intense femtosecond laser pulses in bulk transparent media leads
to a specific propagation regime, termed femtosecond filamentation, which in turn produces …

The pursuit of efficient light sources has stimulated continued effort in the search of materials
and methods for generating white light emission. In addition to the white light produced by …

Optical parametric amplifiers (OPAs) exploit second-order nonlinearity to transfer energy
from a fixed frequency pump pulse to a variable frequency signal pulse, and represent an …

Over the past four years, there has been a surge of activity in the supercontinuum field since
the introduction of various types of microstructure fibers. The main reason for this great …

We report a comprehensive investigation of femtosecond continuum generation in single
crystals of several common laser host materials. The absolute spectral energy density, pulse …

We give a full description of a state-of-the-art femtosecond transient spectrometer. The setup
has been put together under full consideration of all technical and conceptual developments …

The only sustainable energy source on earth is sunlight. Within one hour the current annual
energy demand of the world reaches the surface of earth as sunlight. Many concepts to …

Electron transfer from organic dye molecules to semiconductor− colloidal systems is among
the fastest reported charge-separation reactions. We present investigations on alizarin …

Femtosecond time-resolved spectroscopy on model peptides with built-in light switches
combined with computer simulation of light-triggered motions offers an attractive integrated …

The photodynamics of the two isomers of azobenzene in DMSO after nπ* excitation are
monitored via transient absorption and steady state emission spectroscopy. The excited …
