The development of ultrastable laser sources now allows one to operate on electronic transitions in the optical domain, corresponding to a 5-order-of-magnitude increase in the clock frequency. This article reviews the spectacular …
WebWe report improved frequency measurement of a single 40Ca+ optical clock towards the 10−15 uncertainty level. In contrast with our previous measurement, in which the accuracy was limited by the magnetic field fluctuation, the use of a magnetic shield significantly reduced the observed linewidth of its 2S 1/2 –2D 5/2 clock transition. From frequency … WebAn optical clockwork can thus relate an optical frequency standard to an electronic one, the latter being based on, for example, a cesium atomic clock. Early optical clockworks have been frequency chains , which involved a complicated combination of …
