报告摘要:Mode locking is a well-known laser phenomenon. After mode locking the phases of all lasing modes will be synchronized, and consequently a laser emits a train of optical pulses with narrow pulse width and high peak power. To our knowledge so far there is no laser that emits dark pulses. Those are intensity dips on a CW intensity background. In this talk we will show that a laser can also emit dark pulses. Different types of dark pulse emission were experimentally revealed in erbium-doped fiber lasers and the corresponding dark pulse formation mechanisms were investigated. Numerical simulations have also well reproduced the experimental results.
