Looking at a dark spot, the change in the optical path length difference to go to a bright spot and back to a dark spot is : Question options: ?/4 ?/2 ? 2? 4? Question 2 What is the point of the beam splitter? Question options: Create two paths for the laser light. Split the beam into different wavelengths. Change the distance from the laser to mirrors. Nothing; it's BS. Question 3 Which variables need to be meassured to determine...

P3.4. The spot size is clearly extremely important in determining the power density of a focused laser beam, an important determi- nant of how it may be used in surgery. However, there is a basic limitation on how small a spot one can achieve with a given wavelength laser beam, ; a given diameter laser beam (D); and a lens with focal length, f. This smallest spot sizc is given by: where d is the diameter of the focused laser...

Problem 5: This problem deals with gases used for a He-Ne laser. Consider the Neon transition at 632.8 nm. The upper level of the transition (with respect to ground level of Neon) coincides with a 2s level of Helium that has the energy of 20 eV with respect to the ground level of Helium. The gases are kept at room temperature (300K). We consider only three different energy levels of Neon: ground level, lower level of the laser transition, and...

Problem 3 (25 points) A silicon photodetector has an internal photo responsivity of 0.5 A/Wt wavelength of 850 nm. When photons of wavelength 850 nm are incident normally on this photodetector, some photons are reflected back and some photons penetrate to the detection region and are absorbed by the photodetector. (a) The index of refraction of silicon is 3.45. If the electric current measured by this photodetector is 20 mA, what is the incident optical power? (b) Silicon has a...
