The optically pumped cesium (Cs) frequency standard at the National Research Laboratory of Metrology, Ibaraki, Japan (NRLM), NRLM-4, was modified in various ways in order to improve frequency stability and accuracy, We determined the frequency stabil

A compact light source using a laser diode, whose frequency was stabilized to a saturated absorption spectrum of the Cs‐D2 line (λ=852 nm), was developed for use of an optically pumped cesium frequency standard. The temperature of the laser diode

Present status of laser cooling experiments in NRLM is presented. Laser cooling and trapping experiments for cesium atoms are continued in NRLM to develop an atomic fountain frequency standard. As a first step, we performed Cs atomic beam deceleratio

In this paper we describe a cesium atomic fountain with two-dimensional moving molasses. This method is applicable for multipulse operation of the cesium atomic fountain frequency standard, which will improve the frequency stability and reduce the fr

The velocity distribution of an optically pumped Cs fiequency standard was measured by time-of-flight (TOF) measurement, and it agreed very well with the previous result which was obtained by the long-pulse excitation method. We therefore conclude th
