▎ 摘　　要

A diode-pumped passively Q-switched mode-locking Nd:GdVO4 laser using a chemically reduced graphene oxide saturable absorber was demonstrated. The repetition rate and pulse width of the Q-switching envelopes were 5.7 MHz and 100 ns, respectively, while those of the mode-locking pulses that were modulated in the Q-switching envelopes were 139 MHz and 10 ps. At the maximum pump power of 7W, the average output power was 1.38W, corresponding to a slope efficiency of 25%. (C) 2014 Elsevier B.V. All rights reserved.
