Q-switched Brillouin fibre laser with multi-wall carbon nanotube saturable absorber PROJECT TITLE :Q-switched Brillouin fibre laser with multi-wall carbon nanotube saturable absorberABSTRACT:A Q-switched Brillouin fibre laser (BFL) is successfully demonstrated using multi-walled carbon nanotubes (MWCNTs) embedded in polyvinyl alcohol (PVA) film as a passive saturable absorber (SA) for the first time. The SA is obtained by sandwiching the developed MWCNTs-PVA film between 2 FC/COMPUTER fibre connectors once depositing index-matching gel onto the fibre ends. The proposed Q-switched BFL incorporates a 5 km long dispersion shifted fibre in an exceedingly ring cavity structure to generate Stokes shifted by 0.08 nm from the Brillouin pump wavelength. The BFL starts to come up with a Q-switching pulse train at threshold pump power of five dBm. Because the BP power is varied from 5.0 to 6.zero dBm, the repetition rate of the Q-switched BFL exhibits an increasing trend from 27.75 to 30.twenty one kHz, whereas the pulse width exhibits a decreasing trend from three.25 μs to one.eleven μs. The maximum pulse energy of 0.thirteen nJ is obtained at most BP power of half dozen.0 dBm. Did you like this research project? To get this research project Guidelines, Training and Code...
