LIVERMORE, Calif., June 23, 2021 — A laser-driven semiconductor switch design can theoretically achieve speeds and voltages higher than existing photoconductive devices — potentially enabling communication speeds beyond 5G if the switch were to be miniaturized and incorporated into satellites. The technology was conceived through a joint research effort between Lawrence Livermore National Laboratory (LLNL) and the University of Illinois Urbana-Champaign (UIUC). The research team’s device uses a high-powered laser to generate an electron charge cloud in the base material gallium nitride while under extreme electric...Read full articleRelated content from Photonics MediaARTICLESOptical Measurement Reduces Vibration in High-Power LasersThe Berkeley Lab Laser Accelerator (BELLA) Center at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory has developed and tested an optical system to precisely measure and...Photonics Spectra October 2021 IssueDeep Learning Bolsters Laser-Driven Ion Acceleration StudyResearchers at Lawrence Livermore National Laboratory (LLNL) have applied neural networks to the study of high-intensity short-pulse laser-plasma acceleration, specifically for ion acceleration from...Photonics.com 6/3/2021New Optical Switch Could Lead to All-Optical Signal ProcessingAn optical switch developed by Caltech researchers harnesses the property of optical nonlinearity and aims to enable ultrafast all-optical signal processing and computing.

There is an increasing need to achieve, monitor and maintain higher quality beam characteristics to meet the demands of more sophisticated laser designs and tighter laser process tolerances.For any discussion of laser beam diagnostics, it is first necessary to define some terms that characterize beam properties. Broad definitions can include measurements of laser energy or power,...Photonics HandbookCO2 Lasers: The Industrial Workhorse: Four decades ago, the first industrial use of lasers was for drilling through diamonds or wire draw dies. From that beginning the laser has become an integral part of the conventional technology in many production plants. In the forefront of that revolution has been the CO2 laser, today a varied and sophisticated tool.In the three decades since its introduction, the CO2 laser has become the workhorse of industrial lasers. Today it is available in a range of designs and sizes with output powers of 20 kW and more....Photonics HandbookDriving Diode Lasers: A Straightforward Procedure: Observing the basic principles and understanding the physical behavior of diode lasers helps users operate them correctly and safely.By observing a few simple rules that govern diode lasers’ properties, driving them loses much of its mystery.
