Abstract
A single-frequency low-noise green laser at 509nm is developed for the study of cesium Rydberg atoms. The laser is generated by single-pass second-harmonic generation of a Yb fiber amplifier seeded with an external cavity diode laser (ECDL) at 1018nm in a periodically poled MgO-doped lithium-niobate crystal. An up to 2.03W, 509nm laser is obtained from a 10.04W incident 1018nm laser with a conversion efficiency of 20.2%. The linewidth of the 509nm laser is estimated to be 40kHz according to the measured linewidth of 20kHz of the 1018nm fundamental laser. The relative intensity noise is 0.038% rms integrated from 10Hz to 10MHz.
