【摘要】 当双光子共振激发钾原子到7S能级时,测得了一系列位于红外区的光泵受激辐射和串级受激辐射.由光泵受激辐射与泵浦光的双光子共振四波混频过程,产生了对应于6P-4S和5P-4S的强相干辐射.而这两个相干辐射又具有泵浦光的作用,通过接联的四波混频过程产生位于紫外和可见区的许多相干辐射.文中对测到的红外受激辐射以及紫外和可见相干辐射的产生过程进行了讨论.更多还原

【Abstract】 A series of IR stimulated and c scade stimulated radiation (ws) were detected when the 7S state of potassium was populsted by two-photon resonance excitation. Nine UV coherent radiation lines (wP) were generated through the two-photon resonant four-wave mixing wP=2wL-ws. By the second four-wave mixing process wc = wP-w’s ws", a gereies of UV and violet coherent radiation were formed. The schemes for generating IR stimul ted and UV, violet coherent radiation were discussed in this paper.更多还原
