Menlo Systems, Martinsried, Germany

Menlo Systems GmbH is a spin-off from the renowned Max-Planck-Institute for Quantum Optics. Professor Theodor W. Hänsch, director of the institute, and his co-workers have pioneered a revolutionary and simple technique for measuring the frequency of light: the Optical Frequency Synthesizer. This invention has been called “…the biggest advance in precision electromagnetic measurements since people began to measure laser frequencies in the seventies…”

In 2001, Professor Hänsch, Dr. Ronald Holzwarth, and Dr. Michael Mei founded Menlo Systems GmbH. The founding was guided by the dream and vision of establishing optical frequency comb technology as the most precise measurement tool.

The commercial success story started with the first product in 2002: the Optical Frequency Synthesizer. It enables the user to measure optical frequencies with the highest accuracy with a table top instrument. Numerous world records in precision measurements have been achieved with its base technology, e.g. in the determination of the Rydberg constant.

Second in the product line were the femtosecond fiber lasers. The state-of-the art instruments focus on ease-of-use without sacrificing performance. Various models for applications like medical diagnostics, terahertz spectroscopy, seeding of amplifiers, and test and measurement applications are available.

The ongoing dialog with our customers encourages us to venture into new areas. As a result, whole new products keep emerging and the range of our products now includes THz systems as well cw fiber lasers.

In 2011, starting with more than 60 employees into the second decade of its operation, Menlo System will continue having a strong presence in Europe, North America and Asia.
