This autumn the laser industry will see the retirement of one of its most significant, well-recognised and well-respected figures, Professor Dr Reinhart Poprawe, director of the Fraunhofer Institute for Laser Technology ILT. His departure from the industry will bring to an end what will undoubtedly be referred to as ‘the Poprawe era’ of the ILT – beginning in 1996 when he was first appointed director.


During this 23-year period, countless


innovations were made at the institute, all by highly motivated engineers and scientists to whom Poprawe offered extremely creative freedom and an outstanding infrastructure. In addition, not only was a patent filed at the ILT every three to four weeks during Poprawe’s tenure, but around 30 spin-off companies were also founded in this environment, to which he offered active support during their critical initial phases. A symposium was held in honour of

Professor Poprawe earlier this year on the eve of Laser World of Photonics, where 280 experts from the laser industry paid tribute to his life’s work as a professor of laser technology, as well as to his services to research and bringing together industry and science. In attendance were 60 of the total 200 scientists who earned their doctorate under Poprawe’s supervision, who presented him with a symbolic doctoral cap in recognition of his exceptional work as a professor. On page 12, in addition to speaking with the man himself, we review Poprawe’s extensive career in more detail and learn about the many accolades he has earned over the years. We thank him for his contributions to


the laser industry and wish him all the best for his retirement!


The end of an era...
