Physics 471  Winter Semester 2008
Introductory Information:
Instructor: John Colton, N335 ESC, 4223669. Office hrs: T Th 34 pm, in N335 ESC
Main TA: Ryan Tanner, quantumleap42@gmail.com. Lab/office hours: M 46 pm W 57 (changed!), in/near S415 ESC.
Other TA: Adam Hall, adam.h.mail@gmail.com. Lab/office hours: M 23 pm, in/near S415 ESC.
Change: I have decided not to cover section 7.7. So please change the reading assignment for Feb 29 to be just sections 7.57.6.
Change: There's a small change on dates on the syllabus. I will be out of town March 12 and March 14 instead of Mar 10 and Mar 12. We're going to switch the topics covered on the 10th and the 12th:
Mar 10: Topic = Review (Ch 58). No reading assignment.
Mar 12: Topic = Rays. Reading assignment is 9.1  9.3.
Some major changes to schedule for chapters 10 and 11. Note in particular the reading assignment changes!

Class Notes: (Use at your own risk! They are not guaranteed and the handwritten ones were written for my benefit, not yours.)
Reflectance vs wavelength for some metals (graph from day 7; rest of day 7 notes coming later)
viewgraphs from day 10:
circularly polarized light.doc (in color!)
day 13: review for optics exam 1.doc (includes a listing of which equations you need to memorize vs which ones you don't!)
notes  day 13.pdf (same as the above Word document, but includes my handwritten equations)
start of postexam 1 material:
notes  day 22.pdf (Reading quiz only; for additional day 22 class notes, see the handouts: Dirac delta function.doc and Convolutions.doc)
day 27: review for optics exam 2.doc (sorry, just the Word documentno scan of review with my handwritten notes)
start of postexam 2 material:
notes  days 28 and 29.pdf  These are the "Colton notes" for the two days that Bret Hess taught the class: what I would have taught had I not been out of town.
notes  days 30 and 31.pdf  For day 31, just the quiz is in the pdf file. The rest of the day 31 notes are in this file: Aberrations.doc
notes  days 38 and 39.pdf  For day 38, just the quiz is in the pdf file. The rest of the day 38 notes are in this file: interferograms and holography.doc
notes  day 40.pdf  The last two pages of these notes are things we didn't talk about in class, but which might be interesting to some of you. The second to last page is some comments on that somewhatconfusinglooking graph for semiconductors, emitted wavelengths vs. lattice constant. The last page is my notes on longitudinal cavity modes, which we didn't have time to talk about. You won't be tested on the info. The most important item is that, approximating the cavity as a FabryPerot interferometer, you can show that only an integral number of halfwavelengths can fit inside the cavity. Thus lambda = 2L/n (L = length of cavity, n = integer); this puts a serious constraint on which wavelengths within the overall potential laser emission can in fact lase.
