Investigation of Initial Transmission Effect on Saturable Absorber Optical Performance of Passive Q-Switching Doped Fiber Laser
Zainab Ali Hussein , Abdul- Kareem Mahdi Salih
Abstract
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.
