A laboratory prototype of a pulsed optically pumped (POP) clock based on a rubidium cell with buffer gas is described. This clock has shown very interesting physical and metrological features, such as negligible light-shift, strongly reduced cavity-pulling and very good frequency stability. In this regard, an Allan deviation of y ( ) = 1.2 -1/2 for measurement times up to = 10 5 s has been measured. These results confirm the interesting perspectives of such a frequency standard and make it very
