An investigation is reported of one-dimensional stationary localised r
adiation structures ('laser autosolitons'), which appear in a wide-ape
rture laser with a saturable absorber under conditions of hard lasing
excitation. Bifurcation theory methods are used to find the range of e
xistence of single autosolitons and of their coupled states. It is sho
wn that such structures correspond to a transverse dependence of the f
ield amplitude which is either symmetric and node-free or antisymmetri
c and has a single node. An infinite set of single autosolitons with v
arious widths and transverse amplitude profiles is predicted. It is sh
own that there is an infinite set of 'two-soliton' structures differin
g in respect of the distance between the component autosolitons.
