HALLOA
Hybrid Amplifier Laser for Lidar OperAtions
What is HALLOA?
The HALLOA project is dedicated to the complete development of a pulsed laser system suited to CO₂ (main product), H₂O and wind speed (secondary products) monitoring by space-borne LIDAR using differential absorption method in the 2.05 μm spectral region.
Atmospheric LIDAR generally includes a complex laser design, introducing substantial mechanical constraints. The HALLOA project tackles this issue by designing and developing a so-called hybrid laser that synergistically combines the benefits of compact, alignment-free fiber-based systems with the high-power capabilities of free-space design. This development aims to reach the genuine optical performance required for LIDAR CO₂/H₂O/wind monitoring from space and the TRL6 level using EU-only components and sub-systems.
For non-dependency purpose, the project will establish a European supply chain for such laser as well as new European capabilities in two key technologies: 2.05 µm pulsed fiber amplifier and 79x nm high-power laser diode.
