Abstract

SIMULATION OF SATURABLE ABSORBER MATERIAL POPULATION DENSITY EFFECT ON PULSE CHARACTERISTICS OF PASSIVELY Q-SWITCHING YB+3 DOPED FIBER LASER

*Dunya Saad Hussein and Dr. Abdul-Kareem Mahdi Salih

ABSTRACT

Saturable absorber material (SAM) population density effect on the pulse characteristics of passively Q-switching Yb+3 doped fiber laser has been simulated. Cr+4:YAG used as a SAM in the study. Software computer program buildup in this study for numerical solving of Rate equations model by Runga Kutta –Fehlberg method. The results shows the increasing of saturable absorber material population density lead to increasing each of initial and final values of population inversion density, maximum photons number, and pulse energy. While on another hand lead to decreasing each of rising time and falling time of pulse.
