Lasers have significantly evolved, enabling a wide range of novel applications, including space debris removal, asteroid deflection, and space exploration. This enormous potential is hindered by the lack of international cooperation. This Declaration presents our vision regarding the peaceful use of laser technology in and towards space. We indicate key
steps to achieve this vision and stipulate basic scientific and policy principles. We intend the Declaration to inspire relevant stakeholders and the broader public in the employment of high-energy laser technology for peaceful space related purposes.
