Q-switched EDF LASER Cavity using ITO as Saturable Absorber

Abstract

In this work, we have experimentally reported Q-switched pulse generation by indium tin oxide as a saturable absorber. First the glass slide was placed in electron beam deposition chamber and indium tin oxide layer was coated over the glass slide. Then the indium tin oxide was exfoliated from the glass slide, over the fiber ferrules in erbium doped fiber laser cavity. The Q-switched laser operated at center wavelength of 1562.6 nm. The repetition rate and pulse width were obtained to be 48.31-64.52 kHz and 5.65-4.23 µs, respectively.

“…Recently, Nizamani et al also demonstrated the application of ITO in Q-switched EDFL with the pulse duration of 4.23 μs at 1562.6 nm. [270] Moreover, MgO and PbO are also demonstrated as SAs in ultrafast photonics with great experimental results, which have advantages of low cost and high stability. In 2019, Khaleel et al proposed a fiber laser enabled by MgO served as SAs, where 5.6-ps mode-locked pulses with SNR of 50 dB were observed.…”
