Sacher Lasertechnik GmbH

Über uns

Corporate Information:
Sacher Lasertechnik is a well established business with more than 18 years experience in laser technology. The founder, Dr. Joachim R. Sacher is one of the pioneers of diode lasers with external cavity. The company has developed from a university spin-off to a technology leader in the field of high power tunable external cavity diode lasers. Sacher Lasertechnik U.S. was founded in 1999 for better serving U.S. customers.

Intellectual Property:
Dr. Joachim Sacher was one of the first scientists who recognized the commercial potential of external cavity lasers in connection with antireflection coated diode lasers. The first successful antireflection coatings were realized as early as 1987 at Marburg University. External cavity designs followed within the next years. Key elements of the technology basis are protected by several patent families. Due to these excellent proprietary solutions, Sacher Lasertechnik has become one of the fastest growing laser businesses worldwide.

The Team:
Sacher Lasertechnik is operated by an interdisciplinary research team consisting of physicists, electrical engineers, biologists – all with magna cum laude PhD or Diploma degrees. Research results are frequently presented at international conferences and published in leading industry magazines and science journals since 1989, c/f our publication summary. Up to now, Dr. Sacher has authored or co-authored a large number of articles in the field of external cavity diode lasers and their application. Due to our interdisciplinary research team, we have been able to extend this knowledge base into environmental and life science. Technology references are presented at our website for fast access:
