Dausinger + Giesen
Dausinger + Giesen GmbH develops, designs and manufactures state-of-the-art disc lasers for science and industry according to customer specifications. Our current focus is on ultra-short pulse high-power lasers with pulse times in the picosecond to nanosecond range and outputs of several hundred watts. D+G also sells key components for disk lasers. In addition, Dausinger + Giesen offers consulting services on this topic.

Disk Laser ??
A disk laser is a type of solid-state laser in which the active laser medium is shaped like a disk. This simple geometry of the laser-active crystal, in which the ratio of material thickness to diameter is favourable, enables more effective and uniform cooling, thereby reducing stress.
History
1986: Prof. Dr. Helmut Hügel hired Dr. Adolf Giesen and Dr. Friedrich Dausinger to establish and manage research activities in development of high power laser sources and manufacturing techniques using such lasers, respectively. In the following years the institute’s activities were focused on CO2-Lasers, mainly.
1988: Dausinger took the opportunity of the international conference LIM to present his idea of the ideal laser for welding: Power, efficiency and focusability as a CO2-laser and wavelength like a Nd:YAG-laser. The disk laser was the first one to fulfill these requirements, some years later.
1991: Invention of the disk laser. “Following the basic theory of the MIT scientist T.Y. Fan Giesen laid the foundation of the disk laser with his colleagues Klaus Wittig, Uwe Brauch and Andreas Voß. The idea how it could work came Giesen on the return flight from Fan’s lecture in Los Angeles.” (citation from Laser Community)
2000: Start of first series production of a disk laser at Jenoptik. Since then about 10.000 lasers mainly for medical therapy have been produced.
2002: Berthold Leibinger Innovation Prize for the inventors Giesen, Wittig, Brauch, Voß et al. and for the director of the university institute.
2004: Rank prize for Adolf Giesen for the invention of the disk laser.
2004: Start of series production of high power disk lasers at Trumpf. Since then more than 500 high-power lasers mainly for welding and cutting have been produced.
2004: Foundation of TGSW as a daughter of non profit company FGSW which was at that time closely related to the university institute IFSW.
2007: Foundation of Dausinger + Giesen GmbH. Acquisition of TGSW. Installation of both companies in a former chocolate factory in the center of Stuttgart.
2007: Giesen appointed director of the institute TP of DLR in Stuttgart.
2013: Merging of TGSW into D+G
2017: Soleo Co. Ltd. is becoming main shareholder
About
The Founders
After 21 years full of successful fundamental research and development in University of Stuttgart during which they had been responsible for laser sources and for material treatment techniques, respectively, Adolf Giesen (left) and Friedrich Dausinger (right) founded the startup company Dausinger + Giesen GmbH with the aim to promote the disk laser technology.
Dr Friedrich Dausinger’s background in laser manufacturing, acquired in industry and at university, helps in the development of lasers that meet customer requirements. He is well known in the laser community for his work and achievements.
Dr. Adolf Giesen’s focus is on technical optics. He has conducted research on various laser systems with a wide range of wavelengths and has headed various departments, most recently the Institute of Technical Physics at the German Aerospace Centre (DLR) in Stuttgart. He is also known worldwide for his expertise, and his name is closely associated with the disc laser.
CEO
Dr. Ing. Fabio Ferrario
Fabio Ferrario studied Electronics Engineering in Politecnico di Milano, completing his doctoral studies in Munich TUM and Tel Aviv University.
As a researcher he developed single frequency laser resonators and highly stable atomic clocks, locking these lasers to sub doppler atomic and molecular transitions.
He has been leading Laser manufacturing companies manufacturing medical, industrial and scientific laser sources and systems.
He has been developing high power direct diode systems based on single emitters.
Since 2017 he has been leading technically and financially a company manufacturing laser based selective laser melting additive manufacturing devices.
