A 5 J, 180 ps CO2 laser pulse is channeled by a 17 mm long capillary discharge. Plasma dynamic simulations confirm occurrence of optical guiding conditions along a plasma column of a quasiparabolic radial profile with the minimum axial free-electron density ∼ 1017 cm−3. © 2003 American Institute of Physics.
