Wolfgang Kaiser (17 July 1925 – 20 October 2023) was a German physicist who worked in the fields of laser and solid-state physics.
He was awarded his doctorate in Erlangen in 1952, worked as scientist at Purdue University, and in 1954, he joined the US Army Signal Corps Engineering Laboratories in Fort Monmouth.
[1] Kaiser was internationally recognized for his pioneering work on lasers with ultra-short pulses which find many applications in biophysical and chemical equipment.
[3] The two-photon absorption was postulated by Maria Goeppert-Mayer in 1931 and has become an important method for laser spectrometer applications.
Wolfgang Kaiser has got multiple honorary doctorates, from the Purdue University and others, and he was a member of the Bayerische Akademie der Wissenschaften (Bavarian Association for Science), the National Academy of Sciences, and the Academia Europaea.
