Laser Beam Diagnostics Is a Critical Step in University Research
Laser Beam Diagnostics Is a Critical Step in University Research
The scientific endeavors of our university systems are a vital part of the industrial R&D process that produces many of today’s leading-edge designs and manufacturing processes. The demand to accurately measure these concentrated light forms is endless and limitless. So it is up to the researcher to understand the value of particular lasers that will be considered, which wavelengths are best for the absorption of the material or gasses involved, how much power from the laser source is needed to perform the activity required, and the size, shape and uniformity of the laser beam itself.

Semiconductor Lasers Power Up
Semiconductor Lasers Power Up
Improvements to semiconductor lasers promise big changes, from increases in power to expanded wavelengths. Other innovations could mean faster data rates for a bandwidth-hungry world. Researchers are investigating semiconductor lasers that can be built to output any desired wavelength, enabling new uses. For some applications, what’s important is not just increasing the power that a semiconductor laser can deliver. Instead the key is achieving more intensity per unit area.

Ultrathin Camera Creates Images Without Lenses
Ultrathin Camera Creates Images Without Lenses
A novel camera uses an ultrathin optical phased array (OPA) in place of lenses to enable a thin, light, flexible design. The OPA manipulates light through a large array of light receivers. Each receiver can add a tightly controlled phase shift to the light it receives, enabling the camera to selectively look in different directions and focus on different things.
