Abstract
Diode-laser-pumped, rubidium cell frequency standards have potential short-term stability that is vastly better than their lamp-pumped counterparts. However, AM and FM noise in monolithic laser diodes limit their performance. With extended-cavity, grating-feedback diode lasers, the AM and FM noise can be controlled. In the preliminary work reported here, we have used such a laser to make measurements in two different rubidium cell systems. Measured line Q and signal-to-noise ratios corresponding to (sigma) y((tau) ) equals 4 X 10-13 (tau) -1/2 in a commercial, buffer gas type standard and (sigma) y((tau) ) equals 2 X 10-13 (tau) -1/2 in an evacuated, wall-coated cell are demonstrated. We believe both of these numbers can be improved significantly in a fully engineered and optimized standard.
