Abstract
We apply Lagrangian techniques to dissipative systems described by the complex Ginzburg­Landau equation (CGLE) that is used for modeling
passively mode-locked fiber lasers and all-optical soliton transmission lines. In particular, using Lagrangian equations, we re-derive the known
exact solutions of the CGLE. We also apply the technique to finding approximate solutions for pulsating solitons.

1. Introduction
The dissipative soliton is a new concept that has been de-
veloped quite recently [1]. It includes ideas from three major
sources, viz. standard soliton theory developed since the 1960s,
principles from nonlinear dynamics theory and Prigogine's
