摘要

We report on the evaluation of the performance of self-guiding over extended distances with f/20 and f/40 focussing geometries. Guiding over 39 mm or more than 100 Rayleigh ranges was observed with the f/20 optic at n(e) = 1.5 x 10(18) cm(-3). Analysis of guiding performance found that the extent of the exiting laser spatial mode closely followed the matched spot size predicted by 3D nonlinear theory. Self-guiding with an f/40 optic was also characterised, with guided modes observed for a plasma length of 90 mm and a plasma density of n(e) = 9.5 x 10(17) cm(-3). This corresponds to self-guided propagation over 53 Rayleigh ranges and is similar to distances obtained with discharge plasma channel guiding.
