Unformatted text preview: originates from a point source. By using the hologram equations in the notes and drawing sketches, describe the results when the transmission and reflection holograms are constructed with: (a) U P = U R (b) U P = U R * (c) U P = U O (d) U P = U O * 4 (a) Using energy equations what is the surface temperature versus time for a 150 watt argon laser with a 1 mm 1/e 2 laser spot, at the center of the spot when hitting a silicon surface for a pulse of duration 5x10-6 sec. Give the diffusion depth at the end of the pulse. (b) Repeat (a) but with the material surface being aluminium. (c) Add to the plots the temperature vs time curve for half and one diffusion depth....
