The Laser Lightning Rod (LLR) project aims at laser-based control of atmospheric lightning using laser filamentation. In this work, the development and application of a high-power ultrafast laser system for the LLR project is presented. The laser can deliver 720mJ of pulse energy at a repetition rate of 1kHz. With a pulse duration below 1ps, a peak power of 689GW is achieved. Long-range filamentation and high-voltage discharge triggering was demonstrated at an horizontal experimental campaign. An atmospheric experimental campaign at Mt. Säntis (CH) is planned for summer 2021.
