Tunable Q-switched Erbium-doped Fiber Laser with Titanium Nanoparticles Deposited onto PVA Film as Saturable Absorber

We demonstrate a tunable Q-switched Erbium-doped fiber laser (EDFL) using the newly developed titanium nanoparticles based saturable absorber (SA) for the first time. The Titanium nanoparticles were deposited onto the surface of polyvinyl alcohol (PVA) film via an electron beam evaporation process a...

Electronics Nuclear engineering We demonstrate a tunable Q-switched Erbium-doped fiber laser (EDFL) using the newly developed titanium nanoparticles based saturable absorber (SA) for the first time. The Titanium nanoparticles were deposited onto the surface of polyvinyl alcohol (PVA) film via an electron beam evaporation process and inserted into an Erbium-doped fiber laser (EDFL) cavity to achieve passive Q-switching.

At operating wavelength of 1535 nm, the repetition rate of the self-starting Q-switching pulses is increased from 18.3 kHz to 34.2 kHz while the pulse width is reduced from 19.4 to 10.45 us with increasing pump power from 14.9 to 37.7 mW. The Q-switching pulse shows no spectral modulation with a peak-To-pedestal ratio of 68 dB indicating the high stability of the laser.
