(CNN) The Nobel Prize in Physics has been awarded to a woman for the first time in 55 years, and for only the third time in its history.

Donna Strickland, a Canadian physicist, was awarded the 2018 prize jointly with Gérard Mourou, from France, for their work on generating high-intensity, ultra-short optical pulses. They share the award with an American, Arthur Ashkin, who at 96 becomes the oldest Nobel Laureate, for developing "optical tweezers."

Both inventions had "revolutionized laser physics," the Royal Swedish Academy said.

The Nobel laureates in Physics are announced at the Royal Swedish Academy of Sciences in Stockholm, Sweden.

The announcement comes a day after a senior scientist at CERN, the Geneva-based nuclear research center that is home to a number of Nobel winners, was suspended for saying that physics was invented and built by men.

Strickland said the achievements of women scientists deserved recognition. "We need to celebrate women physicists because we're out there. I'm honored to be one of those women," Strickland said by video link at a news conference following the announcement in Stockholm.
