CPM,Nd:YAG激光器脉宽计算公式的探讨

A Study on a Formula for Computing the Pulse Width of CPM, Nd: YAG Laser

首次将Kumhlke脉宽计算公式应用于CPM,Nd:YAG激光器并对公式进行讨论,代入实验数据由计算机处理作出归一脉宽同小信号增益间的关系曲线,并同CPM染料激光器进行比较,最后提出脉宽公式应用于CPM,Nd:YAG激光器中的修正。

For computing the pulse width of CPM, Nd: YAG laser, Kuhlke's formula is ap- plied for the first time and the formula itself is discussed. After substituting experiment data in the formula, a relationship graph of normalized pulse-width against small signal gain is ploted by a computer. The results are then compared with that from CPM dye laser. A modi- fication of this pulse-width formula for applying in CPM, Nd: YAG laser is proposed finally.
