چکیده انگلیسی
This paper reports a generation of short-pulsed thulium-doped fiber laser (TDFL) in Q-switching operation incorporation of homemade graphene oxide (GO) saturable absorber (SA). The GO SA is embedded with a polymer to form a GO film. A piece of the GO film is integrated into the TDFL cavity for generating a self-started Q-switching operation at 1943â¯nm wavelength. The 3-dB bandwidth, repetition rate, and pulse width of the laser are obtained as 9â¯nm, 15.76â¯kHz-25.08â¯kHz, and 5.08â¯Î¼s-4.2â¯Î¼s, respectively. The maximum pulse energy of 0.698â¯Î¼J obtainable at 344â¯mW pump power, with a peak power of 137.4â¯mW. With a shortest pulse width size at a maximum pump power of 491â¯mW, the higher peak power is determined about 162â¯mW. By integrating our stable Q-switched laser with an optical amplifier, numerous applications such as a material cutting with the eye-safe feature can be realized. This shows a small piece of the GO can modulate a light and use for the pulsed laser industry.
