| Summary: | The aim of this thesis to show beat fiber lasers utilizing a cobalt-doped zinc oxide (Co-ZnO)
based saturable absorber. At first, the generation of Q-switching pulces prepare has been
effectively proposed and exhibited utilizing a cobalt-doped zinc oxide (Co-ZnO) nanorods
as a SA. The proposed Q-switching Erbium-doped fiber laser (EDFL) works at 1559.0 nm
utilizing the Co-ZnO SA film. Furthermore, A passive mode-locked EDFL was then shown
in light of Co-ZnO nanorods SA using modified cavity. A long spool of SMF was
consolidated into an EDFL to measure the depression to work in odd fiber scattering of -
4.571 ps2 administration. A steady self-began soliton pilses prepare was created at limit
direct energy of 219 mW. The central wavelength and redundancy rate of the laser were
1559.5 nm and 1.007 MHz, respectively. The pulse width and most extreme energy vitality
obtained aere 462.8 ns and 5.1 nJ, respectively at a direct energy of 248 mW. The Co-ZnO
nanorods film was created by a straightforward preparing procedure, and it has a balance
profundity of 6 % and immersing force of 60 MW/cm2. |
