3 W high-power laser passively mode-locked by graphene oxide saturable absorber

Journal Article

A novel reflective graphene oxide based saturable absorber is fabricated and used to passively mode locked the Nd:YVO4 ultrafast laser system. The maximum average output power measured is 3.06 W and the optical to optical conversion efficiency is about 25%. The measured pulse duration and repetition rate are 8.8 ps and 84 MHz. The maximum peak power and the single pulse energy of the mode-locking laser are up to 4.1 kW and 36 nJ, respectively. To the best of our knowledge, it is the highest average output power for the lasers mode locked with graphene based absorbers. © 2013 Elsevier B.V. All rights reserved.
