摘要
运用与Na_2(A^1∑^+)和Na(4d)相联属的等频两步混合共振四波混频过程,产生了在322.2nm—325.2nm区内可调谐的紫外相干辐射。实验同时表明,该可调谐相干辐射的强度与钠原子4d→4f碰撞能量转移过程密切有关。
Tunable UY coherent radiation in the region of 322.2 nm-325.2 nm has beengenerated via the equal--frequency two--step hybrid exciation four-wave mixinginvolving the states Na_2 (A^1Σ_u^+)and Na(4d). Meanwhile, the experiment also showsthat the intensity of the tunable coherent radiation is closely related to thecollisional energy--transfer 4d→4f of Na atom.
