Influence of energy level lifetime of Nd:YAG Q-switched laser on laser pulse performance
Fuqiang MA, Yuan LU, Shiyu WANG, Bingbin LI, Peijin SHANG, Jinyou LI, and Zheyuan LI
In the analysis and design of Nd:YAG Q-switched lasers, researchers usually choose to ignore the influence of laser lower level lifetime on pulse waveform. When the laser pulse width is much larger than the laser lower level lifetime, this approximation generally does not bring much deviation. When the pulse width reac
