A microwave frequency reference based on VCSEL-driven dark line resonances in Cs vapor

Abstract

Dark line resonances, narrowed with a buffer gas to less than 100 Hz width, are observed in a Cs vapor cell using a directly modulated vertical-cavity surface-emitting laser (VCSEL). An external oscillator locked to one of these resonances exhibits a short-term stability of ( ) = 9 3 10 12 , which drops to 1 6 10 12 at 100 s. A physics package for a… (More)
