It is a very unusual kind of laser: researchers at the photonics institute at TU Wien (Vienna) have built a device which emits ultrashort flashes of infrared light with extremely high energy.
Researchers have observed quantum effects in electrons by squeezing them into one-dimensional ‘quantum wires’ and observing the interactions between them. The results could be used to aid in the development of quantum technologies, including quantum computing.
The United States and United Kingdom militaries have announced separate deals to develop and deploy laser weapons aboard naval ships.
Most basic physics textbooks describe laser light in fairly simple terms: a beam travels directly from one point to another and, unless it strikes a mirror or other reflective surface, will continue traveling along an arrow-straight path, gradually expanding in size due to the wave nature of light.
This video presents different liquid drops captured at high speeds with the Phantom VEO 640 at 1,500 fps, and the Phantom VEO 710 at 8,000 fps.
Canon’s new Galvano Scanner is a scan head instrument comprised of a number of Canon component technologies including the Galvano motor, scan head, motor driver, control board, and a focusing unit. This new product is developed for precise hole drilling and is able to achieve high-speed and precise laser processing via Canon's original beam shifter technology.
Nothing wakes you up like a good “cup o’ Jo”! Or maybe an ice cold glass of water? Compare the difference between the two with high speed infrared imaging from the X6900sc.
Nothing could beat the feeling of shooting a watermelon and tannerite with an AR15.
Champagne anyone? Prolong the party with this video using the high speed infrared capabilities of the X6900sc.
First Sensor’s new Series 9.5 of avalanche photodiodes (APDs) are designed with an increased sensitivity in the near infrared (NIR) wavelength range up to 950 nm. Due to their fast rise time and very low dark current, these ADPs are ideal for applications with low light intensities and high modulation frequencies such as laser range-finding and laser scanning. Other applications for the photodiodes include safety scanners, 3D-mapping, environmental monitoring, high resolution LIDAR systems for autonomous driving, as well as high speed photometry, and fiber optical communication.

Chemical Mechanical Polishing, or “CMP,” for the planarization of thin films on semiconductor circuitry can be described as the enabling technology for all things digital. This article discusses the importance of this technology within the manufacture of advanced circuits and digital devices, provides a brief history on the technology, and walks through its challenges, characteristics, and real world applications.
Very large marking fields are not practical with steered beam fiber laser marking systems. Marking fields larger than about 12 inches square produce focused spot sizes that are too large to provide sufficient power density for engraving applications, and linewidths too broad for detailed marking applications.In order to achieve large marking fields with steered beam fiber laser marking systems, the information to be marked must be sectioned into “tiles” that are no larger than the marking field. This article discusses the use of galvo drive systems in large field marking and how it is done with good quality hardware and software.
Devices with touch-sensitive interfaces not only sense pressure, but are position-sensitive and force-sensitive. Producing devices with touch-sensitive interfaces requires highly precise test equipment with the ability to repeatedly generate fine-grained motions of exacting force and time profiles. The V-273 family of voice-coil actuators, coupled with the C-413 digital controller, offers developmental and test engineers the perfect tool for quantitatively qualifying touch-enabled devices.
There can be many factors to deal with when looking to utilize the best field of view (FOV). This white paper covers the different types of FOV, the factors that must be considered for choosing a lens for FOV, and what lens focus does to FOV.
Researchers at Georgia Tech Research Institute (GTRI) are utilizing novel photonic integrated circuits (PICs) and other light-based technologies to enhance U.S. electronic warfare (EW) capabilities. Photonics-based technologies offer several advantages over traditional radio frequency (RF) systems in achieving this end.
