Homework Help: Optic and waves design challenge about lasers

  1. May 13, 2014 #1
    "A diode laser has a divergence of 5mrad in the p-direction and 1 mrad in the s-direction. Design an optical system in front of the laser which will make the output circular, and calculate the resulting divergence."
    I am taking the course optic and waves, and the instructor did some explanation about this topic. And I know I should desidn an polarizer. And to make the output circular I should reduce the 5mrad divergence to 1mrad. Then I stuck. I will appreciate if you could help.

    The polarizations given are s and p; if your instructor already went over everything ... why not ask him, or a classmate?
