论文部分内容阅读
A 10 GHz regeneratively mode-lockedfibre laser (RMLFL) at 1550nm constructed with commercially available radio frequency components is presented. Chirp-free hyperbolic secant pulses with duration from 4.4ps to 8ps and output reaching 3.6 mW are acquired. Without any cavity length or polarization maintaining mechanism,the error-free operation of this RMLFL can be carried out in room temperature.
