WebFig. 2 has been observed previously in clocks based on CPT.13,15 When the clock is locked to the zero light-shift value, however, considerably more variation in these param-eters is allowed. In this case, the clock frequency is observed to be largely insensitive at the level of 10−10 to changes in laser temperature of up to 3°C. WebIn CPT clocks based on modulated lasers, all sidebands of the frequency comb can shift the clock frequency [19]. Therefore, it is important that the sum of the AC Stark shifts from all the comb teeth does not change. The total power of the light field is determined by the VCSEL current, and the center frequency depends on both the
