We demonstrate a passively Q-switched Ytterbium-doped fiber laser (YDFL) using a multi-walled carbon nanotubes (MWCNTs) embedded in polyvinyl alcohol (PVA) film as a passive saturable absorber (SA). The SA film is prepared by mixing the MWCNTs homogeneous solution with a dilute PVA polymer solution. It is sandwiched between two FC/PC fiber connectors and integrated into the laser cavity to generate a stable Q-switching pulse operating at wavelength of 1058.6 nm with a threshold pump power of 65.72 mW. The repetition rates of the laser varies from 5.484 kHz to 32.19 kHz as the pump power increases from 65.72 mW to 97.29 mW. The lowest pulse width of 4.2 μs is obtained at the pump power of 69.71 mW while the highest pulse energy of 211.8 nJ is obtained at pump power of 77.75 mW..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
