A new design of ECLD for compact atomic clocks

Cold atom clocks would take great benefits of microgravity environment. In Relation with the clock developments, we work on miniature laser-cooling optical benches. In this article we describe a new design of compact external cavity laser diode, which exhibits up to 80 mW at the output of the ECLD for a diode current of 100 mA and a line width of about 150 kHz.
