On the Demonstration Day hosted at DLR Stuttgart four CLEANSPACE experiments were presented.

 

DEBRIS TRACKING MOCK-UP

The monitoring of space debris with high accuracy is a prerequisite for laser debris removal. Active optical observation systems will provide unprecedented precision, even for cm-class debris, by combining highly accurate determination of angular coordinates with precise distance information from time-of-flight measurements with laser pulses (laser ranging).

The experiment shows a simplified setup to demonstrate how such a 3D position measurement is carried out.

 

LASER PROPULSION DISPLAY

The CLEANSPACE debris removal concept uses a beam of directed laser energy projected from the ground to gently nudge objects into a new orbit or to cause debris to re-enter the atmosphere. Irradiation of the debris particle with high laser fluence induces an ablation process at the particle surface, creating a plasma jet of ablated material, and generating a laser-induced force on the debris particle due to the recoil of the jet.

A “laser wheel”, driven by laser ablative thrust demonstrates the process of laser ablation propulsion.

 

LASER COUPLING DEMONSTRATOR

Debris removal through laser matter interaction requires extremely high pulse energy with relatively high repetition rate and very good beam quality. This last point is very important in order to ensure a high laser energy fluence on the debris to produce the “pushing” effect. All these specifications lead to a very challenging laser design. To overcome material limitations, we developed a key technology allowing the coherent coupling of several laser beams of moderate energy. This coherent beam coupling is able to generate a “super-mode” with the combined energies and a beam quality close to that of a single beam.

A demonstration setup based on active coherent coupling of nine pulsed laser beams is presented.

 

DISK LASER DEMONSTRATION

The centre piece of a laser debris removal system is the laser source. The investigation of suitable laser technologies for future high energy laser sources is a key objective of the CLEANSPACE project.

A demonstration setup based on thin-disk laser technology as well as ceramic materials for laser active media are presented.
