Abstract: The shape of an optical self-similar pulse that propagates in a medium of finite length with noninstantaneous nonlinear absorption is found analytically. The pulse has an asymmetric shape and, in addition, frequency modulation, which confirms that it belongs to a new type of self-similar propagation modes of laser radiation–chirped pulses with a self-similar shape. The existence of pulses of this kind is also confirmed by results of computer simulation.
