Diffraction-free pulsed optical beams via space-time correlations.
Diffraction places a fundamental limitation on the distance an optical beam propagates before its size increases and spatial details blur. We show here that imposing a judicious correlation between spatial and spectral degrees of freedom of a pulsed beam can render its transverse spatial profile independent of location along the propagation axis, thereby arresting the spread of the time-average...
متن کاملFar-field diffraction of pulsed optical beams in dispersive media
Ž . Propagation of a pulsed optical beam a train of ultrashort optical pulses inside a linear dispersive medium is studied in the far field without making the paraxial approximation. This approach permits us to obtain analytical results that are valid for relatively large diffraction angles. Pulse characteristics are found to be affected considerably by the combination of diffraction and disper...
متن کاملGeneration of diffraction-free beams for applications in optical microlithography
A new concept based on a Fabry–Pérot interferometer for the generation of nondiffracting Bessel beams is described and proposed for potential applications in microlithography such as the fabrication of small isolated patterns. It was experimentally demonstrated that the depth of focus can be increased by a factor of about 2, and simultaneously the transverse resolution improved by a factor of 1...
متن کاملGeneration of diffraction-free optical beams using wrinkled membranes
Wrinkling has become a well developed bottom-up technique to make artificial surface textures in about the last decade. However, application of the optical properties of long range ordered wrinkles has been limited to one dimensional gratings to date. We report the demonstration of macroscopic optical focusing using wrinkled membranes, in which concentric wrinkle rings on a gold-PDMS bilayer me...
متن کاملDesigner pulsed beams for enhanced space-time focusing.
We have demonstrated analytically and numerically that at least 10-100-fold enhancements in intensities for similar input energies can be achieved in the focal region of a thin dielectric lens by the use of pulsed beams specifically designed for that purpose.
