The intensity of the HERCULES laser, one of the world's most powerful lasers, is 2.0x1020 W/mm². Granted, the beam pulse lasts for only 30 fs, but if we assume the beam is an electromagnetic pulse, what is its average energy density, and what energy can one pulse deliver to a 1.0-mm² target? (Hint: Be careful with conversions.)
