Post-objective, three-axis, all-digital laser scanning systems provide the large field of view, small spot size, high speed, and high accuracy that next-generation remote laser...
Magnetorheological finishing (MRF) can be used to modify and characterize a surface in an optical system so that it is "perfectly bad," or precisely compensating for all other...
Innovations in data encoding are pushing fiber transmission efficiency close to Shannon's limit -- going beyond will require multipath transmission using multiple cores or multiple...
Just like any other tool, having a bit of insight into how scientific imaging cameras work in the context of the project at hand -- from the simplest brightfield application to...

High-order harmonic generation, a revolutionary tool for studying electronic and nuclear dynamics and molecular structure, is now being extended to new molecular species by optimizing...
While metal and polymer components fabricated using laser additive manufacturing (LAM) are becoming commonplace for jewelry and dental implants, companies are racing to improve...
The great French philosopher Voltaire wrote that we should "judge a person by their questions, rather than their answers." This advice should be applied to the articles we publish...
Here, I interview John Dexheimer, president of LightWave Advisors, who has advised over 100 financings or partnerships in photonics, Internet/software, communications, and electronics...
Every three years, the Optical Society (OSA) holds the Optical Interference Coatings (OIC) conference, always at a location that somehow is also attractive for vacationing. And...
With demand for air conditioning skyrocketing worldwide, reducing the need for electricity to cool buildings is an important part of meeting growing global energy demand.
An alternative terahertz quantum-cascade laser (QCL) developed by an international team of researchers takes advantage of the circular symmetry of concentric circular gratings...
Harbin Institute of Technology researchers have created a high-quality Fabry-Perot interferometer (FPI) cavity with flat axial surfaces suitable for sensing the refractive index...
Scientists at Sciton have demonstrated that erbium yttrium aluminum garnet (Er:YAG) lasers -- due to extremely efficient absorption by water in the skin -- allow doctors to control...
Over the summer of 2013, I interned with MIRTHE -- the National Science Foundation (NSF)-sponsored Engineering Research Center for Mid Infra-Red Technologies for Health and the...
