【Abstract】 In this paper,the approximate and acurate expressions of soliton pulse width with respect to the structure parameters of actively mode-locked laser is obtained for the first time by adiabatic perturbation method and the solving of the path-averaged NLS equation. The two expressions are compared each other and the suitable ranges that could be used of the two expressions aregiven also.更多还原
