The Q-switching Laser Characteristics of Output Pulse under Different Parameters of Cavity Length

In this paper,the technique of the Nd3+:YAG Q-switched laser is firstly introduced,from which the laser pulse emission of energy,pulse-width and peak power are investigated.Then the characteristic curve of different parameters of cavity length is thus obtained.The results illustrate that the changes of the laser cavity length can better adjust the characteristics of the output pulse,which is a good guidance for the flexible application of pulsed laser.
