... The traditional method of describing 3-D imaging properties of a light microscope is by intensity point spread function (PSF) or it’s Fourier transform, the optical transfer function (OTF). However, the more compact way is to use 2-D generalized pupil function. The advantage: the easier way of modif ...

A Ti: Sapphire Planar Waveguide Laser Grown by Pulsed Laser
... The materials growth, undertaken at FO.R.T.H., involved ablation of a single crystal Ti: sapphire target of 0.12 wt % Ti2O3 using a KrF excimer (Lambda Physik LPX200 operating at 25Hz with 500mJ per pulse) focussed to an energy density of •4J cm-2 . The vacuum chamber was evacuated to a base pressu ...

... interaction that leads to attosecond pulses is through the semi-classical re-collision model. A strong infrared light pulse illuminating an atom or molecule creates a “free” electron wave packet by multiphoton ionization, usually approximated by tunneling. Tunneling occurs over a range of phases of ...
