What is a Laser Field?

  1. Apr 10, 2015 #1
    Hello,
    I have encountered this term quite a few times, but I don't really understand what it means. Is it an electric field somehow created by a laser? Could somebody explain this to me?

    I am also unfamiliar with the term. As Dave said, it would help if you could provide some sort of context.

    In the context I normally hear about (e.g. laser wakefield accelerators and strong field laser physics), the term refers to the EM field generated by (generally very short) laser pulses.

    e.g. http://www.europhysicsnews.org/articles/epn/pdf/2002/06/epn02606.pdf

    That's the kind of context I meant it in. Thanks.

    I would say that that's actually a bit too restrictive. It is the EM field emanating from a laser, not necessarily pulsed, although I admit that contemporary work focuses on intense, pulsed lasers.

    Yes. You're totally right, my phrasing was particularly poor there.
