Blue light in rubidium atoms: a glimpse to experiments involving 420 nm radiation

In a variety of experiments, the excitation of thermal and cold rubidium atoms from the ground state mainly involves the transition 5S1/2-5Pj (j=1/2, 3/2) using 795 and 780 nm radiation. In this talk, I will show another excitation route that involves 420 nm radiation. In addition, how this particular transition leads to results as the detection of dipolar forbidden transitions, the generation of Rydberg atoms and a system for laser's emission frequency lock.
