Progress in the Development of a Simple, Laser-Pumped, Vapor-Cell Clock

Abstract:	We are developing a laser-pumped Rb clock with the primary goals of keeping the clock design simple and compact, with low power consumption. We employ a VCSEL diode laser, forcing us to deal with a large PM-to-AM noise conversion problem, and we employ a single cell to lock both the laser wavelength and the VCXO clock frequency. Consequently, we must stabilize the laser using linear absorption spectroscopy, rather than sub-Doppler techniques. Here, we discuss the present status of our laser-pumped clock and our future plans.
