Beam splitters cubes configurations

  1. Oct 12, 2012 #1
    Hello guys,

    I'm not sure this is the right place to ask the question, but I hope someone would have experience with beam splitters cubes.

    If I want to split a laser beam over more than one level with more than one beam splitter cube, so the first beam splitter splits to two beams with 50% of the intensity, and then next cube splits the 50% to two 25%. Is it OK if I just stack the beam splitter cubes behind one another with no separators?

    Thanks for any efforts.

    Although I dont work on lasers, I live with a Laser Technician and he said:
    "Yep...sounds right to me"

    He also said to keep in mind a small amount of loss each time, and work that into your calculations

    You should use non-polarizing beam-splitters, otherwise you have to keep track of the polarization or the splitting fractions in the second layer could be wrong.
