Three-dimensional spatiotemporal focusing of holographic patterns
Two-photon excitation with temporally focused pulses can be combined with phase-modulation approaches, such as computer-generated holography and generalized phase contrast, to efficiently distribute light into two-dimensional, axially confined, user-defined shapes. Adding lens-phase modulations to 2D-phase holograms enables remote axial pattern displacement as well as simultaneous pattern gener...

متن کاملTemporal focusing microscopy.
Axial localization of multiphoton excitation to a single plane is achieved by temporal focusing of an ultrafast pulsed excitation. We take advantage of geometrical dispersion in an extremely simple experimental setup, where an ultrashort pulse is temporally stretched and hence its peak intensity is lowered outside the focal plane of the microscope. Using this strategy, out-of-focus multiphoton ...
متن کاملSpatiotemporal focusing of single-cycle light pulses
We investigate experimentally and numerically the properties of single-cycle terahertz pulses propagating through a focus. The experimental data clearly show changes in pulse shape resulting from the Gouy phase shift and apparent superluminal pulse propagation. The pulses are also considerably distorted by diffraction effects. A solution of the time-domain diffraction integral is necessary to e...
متن کاملObservation of magnetic focusing in two-dimensional hole systems
Advances in crystal growth technology have yielded increasingly pure two-dimensional electron systems (2DESs) at &Gal -&/GaAs heterojunctions. Application of submicron patterning techniques on these materials to obtain laterally confined structures allows the observation of ballistic electron transport. Among such effects stands transverse magnetic electron focusing, where a beam of ballistic e...
