【摘要】 为了满足多频红外激光分离同位素的需要,采用平行的双光栅腔结构,在最佳混合气体体积分数、总压强50.7 kPa、电压27 kV条件下,成功得到了TEA CO2激光器常规带多组双频和三频激光输出。输出的双频波(或三频波)具有良好的空间重叠性和时间同步性,输出波长可调谐且调谐范围较大,激光从一光栅旁边近似地沿平行于腔轴的方向输出,可以满足对一些物质双频(或多频)激发或分离同位素的需要。更多还原

【Abstract】 Double and triple frequency laser outputs have been obtained with the adoption of a parallel grating-grating cavity.The results are derived at a total gas pressure of 50.7 kPa,with the gas combination in volume fraction of 13% CO2,13% N2,74% He under 27 kV voltage.The double or triple frequency output laser possesses fine space overlap and time synchronization,and is tunable within a wide frequency ange.The laser exports beside one of the gratings approximately parallel to the cavity axis.It can meet the requirement of some materials’ double(or multiple) frequency excitation and isotope separation.更多还原
