What to know about Laser stability method advances precision control of electrons with light

Researchers at the University of Oldenburg, in collaboration with Lund University, have developed a laser system capable of generating 200,000 stable light pulses per second. This advancement in controlling the carrier-envelope phase (CEP) allows for more precise manipulation of electrons, potentially aiding the development of ultrafast transistors.
