European researchers are continuing to make advances in the field of integrated atom optics, which seeks to control the flow and interactions of neutral atoms along well-defined...
Used for micromachining, ultraviolet lasers remove material by photoablation, avoiding the thermally induced flaws and degradation produced by longer-wavelength lasers.
The image intensifier as we know it today is a direct result of the military need for night vision. Hence, the manufacturing of such devices is based primarily on a military specificati...
Corning to double capacity for fluoride crystals; Spectrogon AB expands manufacturing capacity; Accent Optical Technologies Inc. closes $15.9-million investment ...
NanoSciences receives SBIR to develop nanowire-based optical detectors; PVS gets state and venture-capital funding; Polaroid and CMD to collaborate on instant digital imaging ...
Coherent electron diffraction may eventually become a standard design and quality-assurance tool for perfecting material defects during the manufacture of semiconductor integrated...
Researchers at Bell Laboratories, Lucent Technologies (Murray Hill, NJ) have generated picosecond self-modelocked (SML) pulses from quantum-cascade (QC) lasers in the mid-infrared...
The identification of proteins and other organic molecules is essential to medical research and diagnostics. In one important method of discovery and analysis, the immunoassay...
To the two-dimensional world of photography, movies add a third dimension. Analysis of everything from a horse's gallop to the motion of atoms skittering across the surface of...
Researchers at the University of Toronto (Toronto, Ont., Canada) are exploring all-optical spin currents in which electrons are driven around and sorted using light in accordance...
Researchers have developed a way of mathematically removing aberrations in the eye by using wavefront-sensing techniques. At the University of Murcia (Murcia, Spain), physicists...
The Massachusetts Institute of Technology (MIT; Cambridge, MA) has committed to build a new fabrication facility for MIT Microphotonics Center researchers.
Researchers at the Technical University of Vienna in Austria claim to have made the first application of an electrically pumped gallium arsenide/aluminum gallium arsenide (GaAs...
Like college students pulling all-nighters to cram for exams and crank out term papers, Congress and President Bill Clinton waited until mid-December to finish many of the appropriation...
The existence of cosmic microwave background radiation (CMBR) in all directions of the sky is well-established evidence that supports the Big Bang model of the early universe....
Although most of the existing methods for pattern recognition through optical correlation have been developed for two-dimensional (2-D) objects, there is a growing need to extend...
Conventional wave optics dictates that light going through an optical lens can never create an image quite as good as the original, because light cannot be focused to a point ...
TOKUSHIMA—The volume of a polymer is determined by the balance between interactions such as electrostatics, hydrophobicity, hydrogen bonds, and van del Waals interactions...
The search has been on for some time to obtain high-quality highly transparent Nd:YAG ceramics that can compete with single-crystal Nd:YAG as laser materials, for the most part...
HYOGO—A group at the Material Science Division of the Electrotechnical Laboratory has developed a magneto-optic waveguide on a gallium arsenide (GaAs) substrate and has ...
GPU Telcom to build fiber network linking six major northeast cities; Calient Networks secures $225 million in third-round financing; KVH Industries completes $5 million private...
Back in 1994, then assistant managing editor Bonnie Heines and I started the Laser Focus World web site, the first web site for any of the PennWell magazines.
Even outside the somewhat esoteric pages of optoelectronics magazines it seems almost impossible to turn around nowadays without bumping into some aspect of the optical communications...
More than 20 years after the initial baseline research, vertical cavity surface-emitting laser (VCSEL) diodes emerged in 1999 into significant commercial use.
Developments in personal computer hardware and Windows-based software are moving the technology for laser-beam profiling into a realm of relatively high user-friendliness and ...
