Integral localized approximation description of ordinary Bessel beams and application to optical trapping forces
(Optical Soc AmerWashingtonEUA, 2011)
Caustic beams from unusual powers of the spectral phase
(Optical Society of America, 2017-10)
Caustic optical beams arising from a spectral phase whose power lies in an unusual range of values less than two are presented. Unlike what happens for conventional phase powers greater than two, it is feasible to generate ...
Dual behavior of caustic optical beams facing obstacles
(American Physical Society, 2017-06)
A full propagation analysis on both fold-type and cusp-type caustic optical beams under various setups of obstructions is theoretically and experimentally performed. It is demonstrated that the self-healing property of ...
Shaping symmetric Airy beam through binary amplitude modulation for ultralong needle focus
(American Institute Of Physics, 2015)
Needle-like electromagnetic field has various advantages for the applications in high-resolution imaging, Raman spectroscopy, as well as long-distance optical transportation. The realization of such field often requires ...
Ultra-long light sheets via curved beam intercrossing
(Optical Society of America, 2020-07-31)
An approach to yield a planar light sheet with thickness below the Abbe’s diffraction limit over ultra-long propagation distances is presented. Such features emerge by an induced interference of the fields associated to ...
Vibrations of L-Shaped Beam Structures With a Crack: Analytical Approach and Experimental Validation
(Wiley Blackwell Publishing, Inc, 2016-06-25)
A crack on a structural member introduces a local flexibility which is function of the crack depth. This new flexibility condition changes the dynamic behavior of the structure. The knowledge of the influence of the crack ...
