Two-photon spectrum of 87Rb using optical frequency comb

The high precision two-photon excitation measurements for 5S1/2 （Fg = 2） to 5D5/2 （Fe = 4 to 1） of 87Rb are per- formed 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...

Zusammenfassung:	The high precision two-photon excitation measurements for 5S1/2 （Fg = 2） to 5D5/2 （Fe = 4 to 1） of 87Rb are per- formed 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.
