I Effect of Collimated lens on Gauss Beam

  1. May 10, 2016 #1
    Hello everyone,

    I am trying to find effect of collimated lens on gaussian beam propagation. Do you know how to solve that? I need any equations ,then going to use them via matlab.

    Thanks

    Hello Ezgie, :welcome:

    I know about a collimator or a collimating lens to get a collimated beam (nice word for parallel beam), but what is a collimated lens ? Could you elaborate a bit on what it is you want to calculate ?

    Hello BvU,

    Thanks for interesting.I am trying to find how collimated lens does affect on gauss beam waist? I mean also intensity. P.S: beam goes to infinity so f is infinity.

    It's a problem with the language. If I understand her correctly, she probably wants to ask how a collimated Gaussian beam is affected after passing through a lens.

    Yes but l need any equations.

    Probably, but Ezgie has to tell us (she looks different alll of a sudden ?) , hence my post #2.

    It is collimating/expanding not parallel.
