Kerr optical effect. This self-focusing further increases power density, until, at a certain threshold, a
low density plasma is created in the material. This plasma lowers the material refractive index in the
center of the beam path and causes the beam to defocus. If the beam focusing…

differential pumping reduces plasma formation at the fiber entrance where the laser intensity is
highest. (In a statically gas-filled hollow fiber, plasma formation at the input side would otherwise
cause a reduction in both coupling…
