Passively Q-switched mode-locking Nd:GdVO4 laser with a chemically reduced graphene oxide saturable absorber
چکیده انگلیسی


• A chemically reduced graphene oxide saturable absorber mirror was fabricated.
• The nonlinear absorption parameters of the absorber mirror were measured.
• Stable Q-switched mode-locking Nd:GdVO4 laser was obtained using the absorber mirror.
• The frequency and duration of the Q-envelopes and mode-locking pulses were measured.

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 7 W, the average output power was 1.38 W, corresponding to a slope efficiency of 25%.
