| Abstract: | The actively mode-locked fiber laser has two kinds of instability.It is proposed a novel method to overcome the short term instability by exploiting nonlinear polarization rotation.The long term instability is removed by feedback used to control fiber cavity length.It is made the actively mode-locked fiber ring laser operation stabily for more than 8 times.The pulse width was 10ps,the spectrum width was 0.317nm,the product of time bandwidth was 0.403,wavelength was 1535～1564nm,the tunable range was 39nm. |
