In his paper on the quantum theory of radiation Albert Einstein introduces the stimulated emission. It is the basic physical effect used in lasers.

Christian Trumpf and two partners purchase the engineering workshop Julius Geiger GmbH in Stuttgart, Germany. The company's logo was based on its products: flexible shafts.

TRUMPF patents the coordinate guidance system for metal sheets - the starting point for the NC controller that the laser machine works with later.

Theodore Maiman generates the first laser light in the USA.

In the same year TRUMPF is referred to by one trade magazine as the "nibbling king" in the growing market of modern, flexible sheet metal processing.

The Haas company and the Frankfurter Battelle-Institute research laser applications for Carl Haas.

Haas begins laser development in-house. The company builds its first solid-state laser.

The new chairman of the Managing Board at TRUMPF, Berthold Leibinger, returns from an information-gathering trip in the USA with a special piece of luggage: a 1 kW CO₂ laser.

TRUMPF introduces the first combined punching-laser machine. CO₂ lasers with 500 and 700 watt output from the USA are the beam sources.

TRUMPF builds its own 1 kW CO₂ laser.

Haas Strahltechnik introduces the first laser light cable for industrial use. Its yellow color has remained the norm.

TRUMPF presents the folded high performance CO₂ laser - still today's best-selling multikilowatt laser.

At the LASER trade show, HAAS-LASER presents its study for the first multikilowatt continuous wave solid-state laser suitable for industrial use.

The disk laser greatly increases the performance potential of diode-pumped solid-state lasers. At the LASER trade show, TRUMPF unveils its first lab machine.

TRUMPF demonstrates the first highly brilliant multikilowatt industrial laser with high performance laser diodes as a direct beam source.
