1. A light source, comprising:

  • a chamber configured to accommodate an ionizable gas;

    an ignition source configured to ionize the gas in order to generate a plasma;

    a laser configured to input laser energy into the plasma such that, under impact of the laser energy, the plasma emits light that forms an output signal of the light source;

    a fiber optical configured to couple the light into a plurality of optical fibers; and

    a first mode scrambler and a second mode scrambler corresponding to at least one optical fiber of the plurality of optical fibers,wherein the plurality of optical fibers comprises;

    first and second optical fibers corresponding to the first and second mode scramblers anda third optical fiber;

    in optical communication with the first optical fiber and the second optical fiber,comprising a larger diameter than a diameter of both of the first optical fiber and the second optical fiber; and

    connected upstream of the first optical fiber and the second optical fiber,the first, second, and third optical fibers, the first mode scrambler, and the second mode scrambler apply a surface homogeneity and an angle homogeneity to the light.
