That's hilarious. However, my question involves impacting the optical imaging system of Cassini which is many, many orders of magnitude easier than overcoming direct illumination from the Sun. The real issue is the matter of beam dispersion rather than having insufficient power, as an astronaut 10 meters away could easily blind Cassini's optical imaging system using a laser pointer.
