Abstract The high precision two-photon excitation measurements for 5S1/2 (Fg = 2) to 5D5/2 (Fe = 4 to 1) of 87Rb are performed by using an optical frequency comb. The two counter-propagating femtosecond pulses (5S1/2→5P3/2 at 780 nm, and 5P3/2→5D5/2 at 776 nm) act on 87Rb vapor, and the Doppler broadened background signal is effectively eliminated. The temperature and power dependences of the two-photon spectrum are studied in this paper.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
