- Abstract
We have developed and approved experimentally a passively Q-switched erbium-doped fibre laser. It is based on the saturable absorption of graphene oxide solution deposited around a microfibre waveguide. The microfibre is fabricated using a standard flame-brushing technique. By controlling the pump power in the cavity, the fibre laser can produce microsecond Q-switched pulses at 1529 nm with the maximum repetition rate 53.47 kHz. With a pumping power of 105.98 mW at 980 nm, each of the laser pulses has the energy about 0.78 nJ and the maximum output power is 42.15 μW.
