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. Intellectual Property: Dr. 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. 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. 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. Specialties: tunable diode lasers, laser controllers, spectroscopy, terahertz
