Scientists shrink lab-grade ultrafast laser on a single chip for making atomic clocks

Scientists at EPFL have managed to shrink a powerful ultrafast laser onto a single chip, a significant step towards creating compact atomic clocks. This innovation not only advances the miniaturization of laser technology but also holds potential for improving precision timing devices used in everything from GPS to quantum computing. The miniaturization of such technology could revolutionize how we approach timekeeping and signal processing, marking a big leap in both scientific research and practical applications.
