Keywords:Physics, Laser, High power pulses, Raman pulse
The effect of output coupler mirrors reflectivity on characteristics of Stokes Raman pulse, which is generated from passive Q-switching intracavity Raman media laser system has been studied. A software computer program based on this study to solve the rate equations of instantaneous performance of the mentioned system (Nd:YVO4, Cr+4:YAG and BaWO4 ) numerically by Runge- kutta-Fehalberg method. The study shows that the energy, duration, and the power of the pulse increasing when the output coupler mirrors reflectivity increasing.
