Momentum-space crystal in narrow-line cooling of 87Sr Project supported by the National Natural Science Foundation of China (Grant Nos. 11474282 and 61775220), the Key Research Project of Frontier Science of the Chinese Academy of Sciences (Grant No. QYZDB-SSW-JSC004), and the Strategic Priority Research Program of the Chinese Academy of Sciences (Grant No. XDB21030100). |
Numerical calculations of the MSC based on broad-line cooling (5s2)1S0–(5s5p)1P1 (461 nm). The calculations are in the horizontal direction at an initial atomic temperature of 3 mK and an interaction time t of 0.5 ms. (a) Final velocity versus initial velocity at detuning frequencies of 50 MHz (black solid), 60 MHz (red dot), and 70 MHz (blue dash). (b) The corresponding spatial distribution. |
