Max Schubert (physicist)

from Wikipedia, the free encyclopedia

Max Schubert (born September 16, 1926 in Plauen ; † April 13, 1998 ) was a German experimental physicist who dealt with nonlinear optics and was a professor at the Friedrich Schiller University in Jena .

Schubert went to school in Plauen and Jena, was a flak helper during the war and then an American prisoner of war. He then worked as an assistant in agriculture near Jena and began studying physics and mathematics at the University of Jena in 1947. His diploma thesis was supervised by Friedrich Hund and was about band structure calculations in solid state physics. Hund also looked after him when he went to Frankfurt himself in 1953. Schubert did his doctorate with Wilhelm Schütz in Jena and became his assistant even before his doctorate. In this position he built up the optical spectroscopy working group in Jena, including Raman spectroscopy . The dissertation was theoretically oriented (improvement of the signal-to-noise ratio), but he also improved the experimental procedures for improving the signal-to-noise ratio in Raman spectroscopy and spectroscopy in the far infrared. In 1962 he completed his habilitation on optimization problems in measurement technology under information-theoretical aspects. In 1963 he became a lecturer and in 1964 a professor in Jena. After joining the laser physics department, he set up the non-linear optics research group in Jena. In 1963 he became acting director and in 1967 director of the Physics Institute in Jena. After the reunification he was director of the Institute for Optics and Quantum Electronics in Jena.

He extended his metrological investigations to quantum optics, where he made important contributions to the problem of phase measurement and non-classical light. In the 1990s he dealt with the phase problem in X-ray diffraction. Schubert always paid attention to a close relationship between theory and experiment and promoted laser physics and quantum optics in the GDR early on.

He wrote a textbook on nonlinear optics with Bernd Wilhelmi (1938–2018), which was also published in an extended version in English.

Schubert was head of the physics section at the University of Jena for several years (1968 to 1970 and 1980/81) and on the Research Council of the GDR. In 1971 he received the National Prize of the GDR , and in 1972 he became a corresponding member of the Berlin Academy of Sciences .
