“…The design of a flashlamp power supply for pumping solid-state lasers was presented in [12,13]. Compactness, losses reduction efficiency enhancement of the pump source power supply and the pump source pulse shape were studied in many researches such as in [2,3,14,15]. Again each subsystem was individually studied.…”

In this paper, we present a pulsed Nd:YAG laser model that accurately predicts the dynamic operations of a passively Q-switched Nd:YAG lasers. We introduce a new implementation technique for the proposed Nd:YAG laser model that provides a compelling incentive for the performance assessment and enhancement for the design of pulsed Nd:YAG lasers using SIMULINK CAD tool. The implemented laser model enables the simulation of the dynamic characteristics of a passively Q-switched Nd:YAG lasers such as carriers, photons, and optical power transient response. The proposed simulation technique is used for predicting the design parameters of practical Nd:YAG lasers. The simulation model also provides a possibility of optimizing the design in regard to optimum output coupler reflectivity, pump power and mirror spacing. Important laser characteristics, such as relaxation-oscillation peak frequency, maximum and minimum repetition rates, delay time and possibly more may be determined using the implemented model. Comparison of experimental and simulation results of the dynamic operation is used to verify the accuracy of the proposed model for designing Nd:YAG laser systems. The measured and published results, such as pumping energy, repetition rate, and output optical power/energy are in good agreement with the simulation results.
