Nicolaas Bloembergen (1920–2017)
Born 1920 CE, died 2017 CE.
Nicolaas Bloembergen (March 11, 1920 – September 5, 2017) was a Dutch–American physicist recognized for his work in developing driving principles behind nonlinear optics for laser spectroscopy. During his career, he was a professor at Harvard University and later at the University of Arizona and at Leiden University in 1973 (as Lorentz Professor). Bloembergen shared the 1981 Nobel Prize in Physics along with Arthur Schawlow and Kai Siegbahn because their work "has had a profound effect on our present knowledge of the constitution of matter" through the use of laser spectroscopy. In particular, Bloembergen was singled out because he "founded a new field of science we now call non-linear optics" by mixing "two or more beams of laser light... in order to produce laser light of a different wave length" and thus significantly broaden the laser spectroscopy frequency band.
