Story summary

Norwegian University of Science and Technology (NTNU) researchers, with École Polytechnique Fédérale de Lausanne (EPFL) and Luxtelligence SA, developed a faster, cheaper, easier to tune microchip laser.
The technology could enhance Lidar in self-driving cars and gas detection systems.
It can be produced at large scale at low cost, enabling small, user-friendly measuring instruments.
The findings were published in Nature Photonics on June 5, 2025.
