Abstract

This paper describes a novel technique to achieve steady-state mode-locking. We used an ultrafast photoconductor as a positive and negative feedback-controlled switch instead of other mode-locked elements such as modulators and dyes. As shown in Fig. 1, this technique does not need very high-precision pump power (Fig. 1)
