Initial Transmission

Study of initial transmission effect on performance of saturable absorber material with Er+3 doped fiber laser was studied. Cr+4: YAG used as a saturable absorber (SA) in the study. Software computer program buildup in this study for numerical solving of rate equations model by Rung - Kutta –Fehlberg method. The study reported that the maximum optical bleaching, Threshold population inversion density are occurs at earlier buildup time of passive Q-switched, and the pulse reaches high power whenever SA characterized by low initial transmission. The study explains that related to the effect of SA initial transmission on the number density of photons feedback in resonator of laser system.

An 1892.4 nm ultrafast passive Q-switched fiber laser is demonstrated by using Thulium-doped fiber (TDF) in conjunction with a multi-walled carbon nanotubes (MWCNTs) as a saturable absorber (SA). The MWCNTs film is sandwiched between two FC/PC fiber connectors and integrated into the laser cavity with 802 nm pump for Q-switching pulse generation. The pulse repetition rate can be tuned from 3.8 to 4.6 kHz while the corresponding pulse width reduces from 22.1 to 18.4 μs as the pump power is increased from 187.3 to 194.2 mW. A higher performance Q-switched Thulium-doped fiber laser (TDFL) is expected to be achieved with the optimization of the MWCNT-SA saturable absorber and laser cavity.
