VCSELS for Rubidium D1 (795 nm)

Mary Salit, Jeff Kriz, Jeff Ridley, and Robert Compton

Abstract:	Vertical Cavity Surface Emitting Lasers (VCSELs) are an enabling technology for miniature atomic devices, including clocks. As VCSELs age, their optical properties vary, introducing timing errors including light shifts and frequency drift. Shorter wavelength VCSELs, such as those used to probe atomic Rb (780 and 795 nm), have been less studied than those which operate at the longer wavelengths used for communications or to probe Cs (852 and 895 nm). It is thus of interest to examine the performance of shorter wavelength VCSELs. In this paper, we survey 795 nm VCSELs supplied by a commercial vendor and evaluate wavelength drift, power drift, and polarization stability, in consideration of requirements for clock stability.
