Graphene oxide absorbers for watt-level high-power passive mode-locked Nd:GdVO 4 Laser Operating at 1

Journal Article

A novel graphene-oxide-based saturable absorber with 12% modulation depth, which is fabricated by the novel vertical evaporation technique, can be used to passively mode locked the Nd:GdVO$ 4 ultrafast laser system. The maximum average output power measured is 1.1 W and it is operating at TEM$ 00 mode. The measured pulse duration and repetition rate are 4.5 ps and 70 MHz, respectively. This low-cost, broadband graphene-oxide-based saturable absorber can potentially be used practically in the high-power mode-locking laser system. © 1983-2012 IEEE.
