Frequency shift of diode lasers stabilized on S-D two photon polarization on RB atoms

In this work, the experimental results of two photon fluorescence and polarization spectrum on S-D transition of Rb-87 atoms and investigation of frequency shift of external cavity diode lasers (ECDL) stabilized on fluorescence and polarization resonance are presented. The influence of gas temperature and external magnetic field to shape of two-photon resonance and laser frequency stabilized on this resonance were investigated.
