Short pulses of laser light traveling in the x-direction with a diameter of 1 mm are incident on a perfect mirror. The pulses are 10^-13 seconds long and have a repetition rate of 10 Hz, each with an energy of 1 mJ. The wavelength of this fentosecond laser is 532 nm.
Estimate the average Poynting vector during the laser pulse.
Determine the maximum electric field during the pulse.
Write down a general function describing the electric field as a function of position and time during the pulse and list the values of all parameters that can be determined for this EM wave.
How many maximum electric field points are there in the pulse?
What is the radiation pressure on the mirror?
