Dj. Spence et Sm. Hooker, Simulations of the propagation of high-intensity laser pulses in discharge-ablated capillary waveguides, J OPT SOC B, 17(9), 2000, pp. 1565-1570
We present the results of simulations of the propagation of high-intensity
laser pulses in discharge-ablated capillary waveguides. The limitations of
this type of waveguide for pulse intensities of the order of 10(16) W cm(-2
) are discussed. However, for higher intensities we describe a new regime o
f quasi-matched golding, that results in significant improvements in guidin
g performance. The effect on quasi-matched guiding of changing the atomic n
umbers of the atoms that compose the plasma waveguide is discussed. Calcula
tions are presented for boron capillaries that show quasi-matched guiding o
ver lengths of 32 mm for an input intensity of 5 x 10(17) W cm(-2). (C) 200
