应用共振跃迁下能级集居数变化现象测定激光波长

Determination of the laser wavelength by the phenomena of laserexcited population change on the resonant transitional lower level

应用激光激发共振跃迁下能级集居数减少,同时发射负信号荧光现象,测定与铀原子605.134nm 跃迁共振的激光波长,本方法与文献[4]的方法结合,可准确可靠测定与一切原子或离子实际存在跃迁共振的激光波长。

The laser wavelength resonated on the 605.134nm transi- tion in atomic uranium was determined by means of the phenomena of laser-excited population decrease and emitted minus fluorescence signal on the resonant transitional lower level.By combining the methods in this work with that in Ref.[4],laser wavelengths resonated on the actually existential transitions in all the atoms and ions might be de- termined accurately and veraciously.
