Abstract
ABSTRACT
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.
