Measurement of the electron-density profile in a discharge-ablated capillary waveguide.
We present the results of time-resolved interferometric measurements of the electron-density profile in a discharge-ablated capillary waveguide. We observe the development of a pronounced axial minimum in the electron-density profile with a relative depth of as much as 60% of the axial electron density. Such a profile is suitable for channeling high-intensity laser pulses.
