Scientists achieve shortest hard X-ray pulses to date

Once only a part of science fiction, lasers are now everyday objects used in research, health care and even just for fun. Previously available only in low-energy light, lasers are now available in wavelengths from microwaves ...

Machine learning helps ease the jitters of high-power lasers

Researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have made a breakthrough in laser technology by using machine learning (ML) to help stabilize a high-power laser.
