We demonstrate two ultra-stable laser systems at 1064 nm by independently stabilizing two 10-cm-long Fabry–Pérot cavities.The reference cavities are on a cubic spacer,which is rigidly mounted for both low sensitivity to environmental vibration and ability for transportation.By comparing against an independent ultra-stable laser at 578 nm via an optical frequency comb,the 1064 nm lasers are measured to have frequency instabilities of 6×10^-16 at 1 s averaging time. 相似文献
