摘要
为了得到9.3μm的激光输出, 采用比较5种CO2同位素气体小信号增益系数的方法, 进行了理论分析。选择同位素气体12C18O2作为射频激励板条波导CO2激光器的工作介质, 进行了实验验证, 得到了9.3μm的激光输出; 并对激光器的工作气压进行优化, 在10.00kPa的工作气压下, 得到了最大96W的功率输出。结果表明, 12C18O2的中心波长在9.3μm附近, 且可得到高功率的激光输出。该研究有利于9.3μm CO2激光器的国产化, 以及提高核心部件的国产化率。
Abstract
In order to obtain 9.3μm laser output, the small signal gain coefficients of 5 kinds of CO2 isotopes were compared. After theoretical analysis and experimental verification, isotope gas 12C18O2 was chosen as the working medium and laser output of 9.3μm was obtained. After the optimization of the working pressure of the laser, the maximum 96W power output was obtained under 10.00kPa working pressure. The results show that high power laser output can be obtained when the central wavelength of 12C18O2 is near 9.3μm. The study is helpful to localize 9.3μm CO2 laser and improve the localization rate of core components.
