Recognized as technologically important materials for optoelectronics, III-nitride wide-bandgap semiconductors are used in light-emitting diodes (LEDs) with emission wavelengths from the ultraviolet to amber, and blue/UV-emitting laser diodes.1 These materials are excellent for photonic devices because of their large energy bandgaps, their highly efficient light emission, and their ability to b...
متن کاملNanopore tomography of a laser focus.
We demonstrate that the ionic current through a solid-state nanopore can be used to measure at single nanometer resolution the three-dimensional intensity profile of a laser directly in the focus of a microscope objective. We find a linear dependence of the ionic current on the incident laser power since the laser-induced heat increases the temperature locally in the solution. Our data show a t...
متن کاملLaser-guided intraoral radiography: A future focus
the past few decades, rapid changes have taken place in the fields of science and technology. Simultaneously , great progress has been made in research work on laser applications. Today, laser use ranges from simple applications such as recording prices of groceries to complex applications such as measuring distance to the moon and laser-guided warfare. 1 In the field of dentistry, the research...
متن کاملUnsolved problems in observational astronomy . II . Focus on rapid response – mining the sky with “ thinking ” telescopes
The existence of rapidly slewing robotic telescopes and fast alert distribution via the Internet is revolutionizing our capability to study the physics of fast astrophysical transients. But the salient challenge that optical time domain surveys must conquer is mining the torrent of data to recognize important transients in a scene full of normal variations. Humans simply do not have the attenti...
متن کاملVector fields in a tight laser focus: comparison of models.
We assess several widely used vector models of a Gaussian laser beam in the context of more accurate vector diffraction integration. For the analysis, we present a streamlined derivation of the vector fields of a uniformly polarized beam reflected from an ideal parabolic mirror, both inside and outside of the resulting focus. This exact solution to Maxwell's equations, first developed in 1920 b...
