Abstract—We report on a passively Q-switched and mode-locked Nd:YVO4 laser using a novel low-cost wall-
paper graphene oxide absorber. Sandwich structured wallpaper graphene oxide absorber was constructed by a
high transmission mirror, a piece of wallpaper graphene oxide absorber and a reflective mirror. The average out-
put power of 310 mW of passively Q-switched and mode-locked laser was successfully achieved. The repetition
rate and pulse width of the Q-switched envelope were 213 kHz and 770 ns, respectively. The repetition rate of
passively mode-locked pulse within the Q-switched envelope was 81.3 MHz with the pulse energy of 3.8 nJ.
