【Abstract】 For a laser diode array(LDA) side-pumped solid-state lasers,based on the rate equation of four level systems,the simulation of side pumped Nd∶YAG laser is established.The relationship between the output parameters and the pump parameters has been analyzed.It can be seen that the pump light parameters such as the radius of the rod and the distance between the laser diode array and the rod are main factors to the beam quality of the laser.Computed results indicate that the position of the pumping LD and the radius of the crystal rod can influence the beam quality.更多还原
