摘要
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. (C) 1999 Optical Society of America OCIS codes: 230.7370, 120.3180, 350.5500, 350.5400, 140.7240.
