| Abstract(in English) | Regenerative mode-locking is a technique of self-oscillation for pulsed lasers, where the electrical clock signal extracted from the output pulse train of the laser is used as the driving source of active mode-locking. In fiber lasers, this technique is co-used with harmonically mode-locking to achieve a high repetition rate, whereas stable clock extraction is necessary for stable operation of the laser system．We experimentally demonstrate a regeneratively and harmonically mode-locked fiber laser employing clock extraction from the second-harmonic of the repetition frequency. The proposed laser showed much better stability than did a laser employing conventional clock extraction. In this paper, we report our experiments on the laser system, and discuss reasons for the stable operation. |
