Nickel oxide nanoparticles for Q-switching pulses generation

We report an observation of Q-switching pulses train in passively Q-switched Erbium-doped fiber laser (EDFL) employing Nickel oxide (NiO) film as a passive saturable absorber (SA). The NiO was prepared by the facile sonochemical method. It is embedded into Poly(ethylene oxide) (PEO) film, which is t...

Summary:We report an observation of Q-switching pulses train in passively Q-switched Erbium-doped fiber laser (EDFL) employing Nickel oxide (NiO) film as a passive saturable absorber (SA). The NiO was prepared by the facile sonochemical method. It is embedded into Poly(ethylene oxide) (PEO) film, which is then sandwiched between two fiber ferrule connectors to form a fiber-compatible NiO SA. The Q-switched laser generates a stable pulses train operating at 1558 nm as the pump power was increased above the threshold pump power of 144 mW. The laser has a pulse repetition rate tunable from 50.3 to 66.0 kHz with the increasing pump power from 144 mW to 240 mW. The maximum pulse energy and minimum pulse width of 5.6 µs were observed at pump power of 240 mW. The SNR of the fundamental frequency was obtained at 67 dB, indicating the stability of the laser. These performances indicates a good prospect of NiO as an excellent SA for operation in 1550 nm region.
