The first chair of nonlinear optics in Germany was held by Max Schubert (1926–1998), who was appointed to the University of Jena in 1964. Together with his student, the physicist Bernd Wilhelmi (1938–2018), Schubert wrote an ›Introduction to Nonlinear Optics‹, a textbook that subsequently became an international standard work.
Six years after Anne L’Huillier had discovered high harmonics, Gerhard Paulus (*1966), who was appointed to the University of Jena in 2007, demonstrated the corresponding effect in photoionization. In 2015, Anne L’Huillier became the first female honorary doctor of the Faculty of Physics and Astronomy at the University of Jena.
As it stands, the most advanced school of thought in nonlinear optics is the field of relativistic laser physics. When the laser fields are so strong that the electrons are accelerated to almost the speed of light, a whole new class of characteristic effects is produced. The first chair in this field is currently held by Malte Kaluza (*1974) at the University of Jena.
