Biography
About
Alfred Kastler was born in Germany on 3 May 1902 but became French, and spent his career coaxing atoms to reveal themselves. He developed optical pumping, a method of using light to shift atoms into higher energy states so their behavior could be studied with new precision. The work opened pathways into quantum mechanics and laser technology. Physics gave him its highest recognition: the Nobel Prize. He died 7 January 1984, decades after the technique he invented became fundamental.
