A powerful military laser produces 50 MW of power in short bursts that last 2 x 10-10 seconds each in a non-collimated beam of radius r = 0.88 mm. In a vacuum, the frequency of the laser’s radiation was measured at 6 x 1012 Hz. How much energy is contained in a single laser pulse and what is the force of impact on a target with radius R = 2 cm assuming 100% of the energy is reflected by the target?
