LASER 2022: Leibniz Institute and Fraunhofer ILT create lasers for climate research

Partners report on how their laser measurement devices for exploring the atmosphere were received in Munich.

The Fraunhofer Institute for Laser Technology (ILT), based in Aachen, Germany, debuted new laser systems it has developed for researching Earth’s atmosphere at last month’s LASER World of Photonics in Munich. This week, the ILT reported that: “many of the 15,000 visitors showed great interest in the systems exhibited, including lasers for space applications as well as for ground-based measurements.”

Over the past few years, a team of researchers from ILT and the Leibniz Institute for Atmospheric Physics IAP, Kühlungsborn, have developed a new generation of laser measurement devices for exploring the atmosphere. At Munich, they presented the latest generation of these mobile systems, which can measure wind and temperature from the ground to altitudes above 100 km.

The core of this Doppler lidar system is a diode-pumped alexandrite laser. With this beam source, the engineers at ILT could develop the instrument – including the transmitting and receiving optical system – in a compact size, only 1m x 1m x 1m.

The precursor, based on a flashlamp-pumped alexandrite laser, was developed at Leibniz IAP and installed in a shipping container,” said Dr. Michael Strotkamp from Fraunhofer ILT in Aachen. “With the newly developed diode-pumped beam source, our system is clearly superior to the old flashlamp-pumped systems, also in terms of stability and lifetime.”
