Graphene Oxide Film as Passive Q-switcher in Erbium-doped Fiber Laser Cavity
View through CrossRef
All-fiber passively Q-switched fiber lasers have been demonstrated by using graphene oxide (GO) Q-switcher for possible applications in telecommunication, laser processing, fiber sensing and medical community. The GO material was obtained through a modified Hummers method from expanded acid washed graphite flakes and it was embedded into a polyvinyl alcohol (PVA) film to form a saturable absorber (SA) device. The Q-switched pulse operates at 1563.3 nm with a repetition rate that can be tuned from 44.33 kHz to 61.77 kHz as the pump power changes from 39 mW to 96 mW. The highest repetition rate of 61.77 kHz is achieved at a pump power of 96 mW and it is observed that the Q-switched pulse produced maximum pulse energy of 0.054 nJ and pulse width of 5.57 ?s at 96 mW pump power.

Title: Graphene Oxide Film as Passive Q-switcher in Erbium-doped Fiber Laser Cavity
Description:
All-fiber passively Q-switched fiber lasers have been demonstrated by using graphene oxide (GO) Q-switcher for possible applications in telecommunication, laser processing, fiber sensing and medical community.
The GO material was obtained through a modified Hummers method from expanded acid washed graphite flakes and it was embedded into a polyvinyl alcohol (PVA) film to form a saturable absorber (SA) device.
The Q-switched pulse operates at 1563.
3 nm with a repetition rate that can be tuned from 44.
33 kHz to 61.
77 kHz as the pump power changes from 39 mW to 96 mW.
The highest repetition rate of 61.
77 kHz is achieved at a pump power of 96 mW and it is observed that the Q-switched pulse produced maximum pulse energy of 0.
054 nJ and pulse width of 5.
57 ?s at 96 mW pump power.
