Maria Goeppert Mayer became the second woman to win the prize in 1963, for the theoretical development of the nuclear shell model, a half of the prize shared with J. Hans D. Jensen (the other half given to Eugene Wigner). Donna Strickland shared half of the prize in 2018 with Gérard Mourou, for their work in chirped pulse amplification beginning in the 1980s (the other half given to Arthur Ashkin).

In 2023, Anne L'Huillier shared the prize in equal parts with Pierre Agostini and Ferenc Krausz for their experimental contribution and development of attosecond physics. L'Huillier is the first female laureate to receive 1/3 of monetary award of the Nobel Prize in Physics (Curie, Goeppert–Mayer, Strickland and Ghez received 1/4).
