This paper discusses methods for characterization of high power lasers. Specifically, these methods have been
developed for the High Energy Laser Joint Technology Office and used for independent, government-sponsored testing
in the 25 and 100 kW phases of the Joint High Power Solid State Laser program. Primarily this paper addresses
measurement of power and beam quality.
The High Energy Laser Joint Technology Office (HEL-JTO) was established in 2000 for the purpose of developing and executing a comprehensive investment strategy for HEL science and technology that would underpin weapons development. The JTO is currently sponsoring 80 programs across industry, academia, and government agencies with a budget of approximately $60 million. The competitively awarded programs are chosen to advance the current state of the art in HEL technology and fill technology gaps, thus providing a broad capability that can be harvested in acquisition programs by the military services.
