Paper Abstract

Time-frequency applications need high accuracy and high stability clocks. Compact industrial optically pumped Cesium beam standards are promising to address various demands. In this context we are developing Al-free active region distributed-feedback diode (DFB) lasers at 852nm and 894nm for, respectively, the D2 and D1 line Cesium pumping. In order to address the long term reliability of these lasers, long duration ageing tests (more than one year targeted) are being carried out for both wavelengths at 20mW and 25°C. The laser diodes have been ageing for 4950 hours and 3120 hours respectively with very low increase of the operating current.
