摘要：

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 sigma (y)(tau) = 9.3 x 10-12/root tau, Which drops to 1.6 x 10(-12) at 100 s, A physics package for a frequency-reference based on this design could be compact, low-power, and simple to implement.
