摘要

本文比较了十种钠原子激发方案的效率，这些方案有可能用于产生钠多色激光导星（PLGS）和单色激光导星（LGS）。结果表明，利用单光子激发的级联荧光效应在钠蒸气中产生 LGS 时，最合适的是在波长为 330.237 nm 时激发的 42P3/2 ← 32S1/2 转变，其 LGS 特性最高，而与波长为 588.995 nm 的单色 LGS 相比，效率则降低了两个数量级。

Comparison of the Efficiency of Sodium Atom Excitation Schemes for Generating Monochromatic and Polychromatic Laser Guide Stars

The efficiency of ten sodium atom excitation schemes that can potentially be used to generate a sodium polychromatic laser guide star (PLGS) and a monochromatic laser guide star (LGS) is compared. It is shown that for creating an LGS in sodium vapor using the cascade fluorescence effect with single-photon excitation, the most suitable is the 4²P_3/2 ← 3²S_1/2 transition excited at a wavelength of 330.237 nm and demonstrating the highest LGS characteristics, while the efficiency decreases by two orders of magnitude compared to a monochromatic LGS at a wavelength of 588.995 nm.
