Lasik eye surgery uses pulses of laser light to shave off tissue from the cornea, reshaping it. a typical lasik laser emits a 1.0-mm-diameter laser beam with a wavelength of 193 nm. each laser pulse lasts 20 ns and contains 2.0 mj of light energy.
part a: what is the power of one laser pulse?
part b: during the very brief time of the pulse, what is the intensity of the light wave?

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
