It is show that, for the ultraviolet pre-ionization TEA CO2 Laser, the absorption of two photos in the process of the photo-ionization plays an important role.
研究表明，在紫外预电离tea CO_2激光器中的光离化过程中双光子吸收起着十分重要的作用。

Thetheoretical calculations and the experiments suggest that, double pre-ionization has an obvious advantage for increasing the initial electron density between the main electrodes.
理论计算与实验表明，双预电离在提高主电极间初始电子密度方面存在着明显的优越性。

In order to improve the output quality of the laser, we brought forward the concept of double pre-ionization, which is beneficial for the effective excitation of the laser media in the resonator.
