Soft x-ray lasing with a gain length GL{approx_equal}5.5 was demonstrated in hydrogenlike LiIII at 13.5 nm (2-1 transition) in a 5 mm long LiF microcapillary using a 50 mJ, 250 fs UV laser beam at a 2 Hz repetition rate. The initial plasma was created in the 0.3 mm diameter microcapillary by a low power Nd/YAG laser. The strongly nonlinear increase of the 13.5 nm line intensity with increasing microcapillary length was compared with a linear increase of the LiIII 11.4 nm (3-1 transition) line intensity. {copyright} {ital 1996 The American Physical Society.}
