Abstract :
Measurement and modeling of single-walled carbon nanotubes (SWCNTs) based saturable absorber (SA) on stabilizing and shortening mode-locked fiber lasers are presented. The concentration and thickness effect of SWCNTs SA on stabilizing and shortening passive mode-locked pulse is investigated experimentally. Haus master equation is applied to simulate the pulse characteristics to understand the dynamic operation of passive mode-locked fiber lasers. The simulation results are in good agreement with the experimental results for the spectral bandwidth and pulse width depended on the thickness and concentration of SWCNTs SA. A limit of spectral bandwidth of 6.04 nm and pulse width of 440 fs in passive mode locking lasers is obtained. A comprehensively study of pulse characteristics of passive mode-locked fiber lasers provides a guide to fabricate an effective SWCNTs SA for use in many carbon nanotubes based photonics devices.
