Results of numerical simulation of the formation of pulsating solitons in a
laser with relaxation of gain and saturable absorption are presented. The
regions of relaxation parameters are found in which stationary pulsating so
litons and solitons with strong modulation of the pulsation amplitude are o
bserved. Examples of multiple subsequent doubling of the oscillation period
, caused by changing relaxation parameters, are presented. (C) 2001 MAIK "N
