Lasers can be utilized to drill or cut material. One such laser generates a series of high-intensity pulses rather than a continuous beam of light. All pulse contains 0.500 J of energy and lasts 10 nanoseconds. The laser fires ten pulses per second.

a. What is the power of the laser light through one of the pulses?

b. What is the average power of the laser (ie. The total energy delivered per second)?

c. A lens focuses the laser beam to a circular spot 10. μm in diameter. What is the light intensity?

d. What is the ratio of the laser intensity on the target to the intensity of the sun at midday (which is about 1100 W/m2)
