基于两步混合激发Na_2-Na系统的可调谐红外受激辐射

TUNABLE IR STIMULATED RADIATION GENERATED BY TWO-STEP HYB1RD EXCITING IN Na_2-Na SYSTEM

本文报道了与两步混合激发Na_2-Na系统相联系的受激电子喇曼散射过程产生了在3.38—3.46μm范围内连续可调谐的红外受激辐射的研究结果。对这种可调谐红外受激辐射的产生机制和实验结果作了仔细的分析和讨论。 同时,还计算了该红外受激辐射的相对强度并与实验结果进行了比较。最后指出这一工作与前人所做工作的不同之处及所具有的显著特点。

We report the generation of turnable IR stimulated emission covering 3.39-3.46 um, by using a new exciting mechanism called "two-step hybird exciting" in sodium molecular-atomic system. We analyse and discuss carefully this IR emission. The computed relative intensity of the IR emission varies with the pumping deturning. The computational results matched well with experimental data.
