摘要
本文从理论上提出了在激光工作物质增益线型为罗伦兹线型,吸收物质线型为高斯线型的情况下,利用斯塔克效应的CO_2激光稳频系统中的鉴频曲线的计算模型,以该模型为基础,具体地计算了吸收物质为NH_2D气体的鉴频曲线。结果表明:激光工作物质线型对鉴频曲线的形状有较大的影响。与不考虑激光线型影响的情况相比较,鉴频曲线的线性鉴频范围变小,对称性变差。
Taking laser gain profile as the Lorentz lineshape and the broadening profile of absorption gases as the Gauss lineshape, we put forward the mathematical model of the frequency discriminating curve of CO_2 laser frequencystabilized using Stark effect. On the basis of the model, we obtain the frequency discriminating curve of CO_2 laser frequency using NH_2D Stark effect by computer calculation. It is showed that the laser gain lineshape greatly influences the thape, the linear range and the symmetry of the frequency discriminating curve.
