Reference excerpt

Wolfgang Kaiser (17 July 1925 – 20 October 2023) was a German physicist who worked in the fields of laser and solid-state physics.

Biography Wolfgang Kaiser was born in Nürnberg on 17 July 1925. 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. From 1957 to 1964, Kaiser worked at Bell Laboratories in Murray Hill. In 1964, he became a professor for experimental physics at the Technical University of Munich, where he performed research on laser physics. Kaiser died on 20 October 2023, at the age of 98.

Research Kaiser was internationally recognized for his pioneering work on lasers with ultra-short pulses which find many applications in biophysical and chemical equipment. For example, he showed the molecular reactions regarding the photochemistry of bacteriorhodopsin in photosynthesis. He was involved in the development of ruby lasers and discovered the two-photon absorption with C. G. B. Garrett. The two-photon absorption was postulated by Maria Goeppert-Mayer in 1931 and has become an important method for laser spectrometer applications. Furthermore, Kaiser and his colleagues looked at, and simulated Raman scattering, Brillouin scattering, and the duration of existence of phonons in solid-state matter using Raman spectroscopy. Other topics Kaiser worked on include semi-conductors as well as nonlinear optical issues.

Worked examples

Example 1 — a first encounter with Wolfgang Kaiser (physicist)

Start with the simplest possible case. Write down what Wolfgang Kaiser (physicist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wolfgang Kaiser (physicist) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wolfgang Kaiser (physicist) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wolfgang Kaiser (physicist)

In research: Wolfgang Kaiser (physicist) appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Wolfgang Kaiser (physicist) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Wolfgang Kaiser (physicist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1925 births, 2023 deaths, 20th-century German physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Wolfgang Kaiser (physicist) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
