Laser Focus World is an industry bedrock—first published in 1965 and still going strong. We publish original articles about cutting-edge advances in lasers, optics, photonics, sensors, and quantum technologies, as well as test and measurement, and the shift currently underway to usher in the photonic integrated circuits, optical interconnects, and copackaged electronics and photonics to deliver the speed and efficiency essential for data centers of the future.

Our 80,000 qualified print subscribers—and 130,000 12-month engaged online audience—trust us to dive in and provide original journalism you won’t find elsewhere covering key emerging areas such as laser-driven inertial confinement fusion, lasers in space, integrated photonics, chipscale lasers, LiDAR, metasurfaces, high-energy laser weaponry, photonic crystals, and quantum computing/sensors/communications. We cover the innovations driving these markets.

Laser Focus World is part of Endeavor Business Media, a division of EndeavorB2B.
