We report the results of studying a compact laser system designed for manipulating a quantum state of the optical qubit based on the 2 S 1/2 → 2 D 3/2 quadrupole transition in the 171 Yb + ion at a wavelength of 435.5 nm. An emission power of the laser system reaches 500 mW at λ = 435.5 nm and the relative frequency instability of at most 3 × 10 -15 is achieved at averaging intervals from 0.5 to 50 s with a subtracted linear frequency drift. The compactness of the developed system makes it possible to employ it in transportable systems including optical clocks.

我们报告了研究紧凑型激光系统的结果，该系统设计用于在171 Yb +离子中以435.5 nm的波长基于2 S 1/2→2 D 3/2四极跃迁来操纵光学量子位的量子态。激光系统的发射功率在λ= 435.5 nm时达到500 mW，并且在平均间隔为0.5到50 s的情况下，通过减去线性频率漂移，可以实现至多3×10 -15的相对频率不稳定性。所开发系统的紧凑性使其可以在包括光学时钟在内的可移动系统中使用。
