Chaotic control for the fiber laser system was discussed in this paper.It is easy to realize stable control for fiber laser chaotic system via linear feedback control.Using this linear feedback control,the single-model laser chaotic system is not chaotic.The linear feedback control function was given,and feedback coefficients were obtianed theoretically.The investigation results show that,the single-model laser chaotic system is not chaotic and has the required arbitrary stable outputs and periodic orbits choosing suitable linear feedback control function and feedback coefficients.Another more important results are that control results are made certain beforehand by assured linear feedback control function and feedback coefficients.
