Lay Summary (German)

Lead
Frequenzkämme bieten einzigartige Möglichkeiten in Anwendungsgebieten der Metrologie, Spektroskopie und Sensing. Die Marktgröße der Gasdetektion beträgt derzeit 361 Millionen Dollar und sieht einen beeindruckenden Anstieg von rund 50% pro Jahr vor. Es gibt eine starke Nachfrage nach günstigen Gasdetektoren für die Erfassung von Abgasbelastung, Luftverschmutzung durch toxische Gase sowie menschliche Atemanalyse für die frühzeitige Erkennung von Krankheiten. Ziel dieses Projekts ist es, den günstigen Frequenzkamm zu entwickeln, der in diesen Anwendungen eingesetzt werden kann.
Lay summary

Das Projektziel war es, eine kompakte, kostengünstige, ultrastabile Frequenzkammquelle auf Basis der Faserlasertechnologie zu entwickeln. Wir haben einen kostengünstigen Faserlaser-Prototyp mit hoher Wiederholrate und einer Grundfläche von 10 cm x 10 cm entwickelt. Wir haben unsere eigene Stabilisierung und Treiberelektronik entwickelt, um unseren Faserlaser mit unserer Technik zu stabilisieren. Auch im Vergleich zu den bestehenden Produkten auf dem Markt wurden unterschiedliche Zulassungen angewendet. Wir haben uns darauf konzentriert, die Schwachstellen des Prototyps zu verbessern, um ihn marktreif zu machen.

Lay Summary (English)

Lead
Frequency combs provide unique opportunities in metrology, spectroscopy and sensing applications. The market size of gas detection is currently 361 million $ and is seeing an impressive growth of around 50% every year. There is strong demand for affordable gas detectors for detection of pollution dispersion, toxic gases for homeland security and chemical leaks, and human breath analysis for early illness detection. The aim of the project is to develop an affordable frequency comb that can be used in these applications.
Lay summary
The aim of the project has been to develop compact, affordable, ultrastable frequency comb source based on fiber laser technology. We have developed a low-cost high repetition rate fiber laser prototype with a footprint of 10 cm x 10 cm. We have developed our own stabilization and driver electronics to stabilize our fiber laser using our technique. Different approcahes have also been applied for comparison to the existing products in the market. We focused on improving the weak points of the prototype to prepare it for the market.

Abstract

Optical frequency combs are essentially a combination of millions of lasers with different colors, propagating all together. They look like the teeth of a 'comb', each representing a frequency, hence the name 'Frequency comb'. The first demonstration of this optical tool was honoured with the Nobel Prize in Physics in 2005. These frequency combs provide unique opportunities in metrology, spectroscopy and sensing applications.However, there is a huge challenge for market penetration: with costs easily reaching more than 100,000 €, the required lasers are too expensive for most real-world applications and OEM integration. One of the Nobel prize laureates has patented the key technique for stabilization. His co-owned company Menlo Systems, Germany, has currently dominant market control, preventing competitor companies from entering in for many years. There are many potential applications set forth to use this optical tool, waiting for an affordable solution to take the next steps.We developed a method allowing a new way of stabilizing frequency combs. The new method allows for a frequency comb with better performance in terms of noise and higher stability. With Bridge - Proof of Principle, a suitable prototype will be developed allowing us to enter the market.
