Paper Abstract

A black phosphorus saturable absorber (BP-SA) fabricated by a modified electrochemical delamination strategy exfoliation process was inserted inside a Yb-doped ring laser cavity. Based on this BP-SA, a stable nanosecond pulse laser could be achieved. When the pump power increased to 151 mW, a fundamental repetition rate of 6.78 MHz and 3.38 ns pulse began to initiate. The pulse could initiate stably at least 3 hours each day for a week. These demonstrations indicate that the related thin-film BP SA preparation method would make the construction of pulse laser more efficient and benefit industrial community in the future.
