| 摘 要： | Frequency shifts of the acetylene saturated absorption lines at 1.5μm with temperature, gas pressure and laser power have been investigated in detail. The second-order Doppler effect, the recoil effect, the Zeeman effect, the pressure shift and the power shift are taken into consideration. The magnitudes of those shifts caused by various effects are evaluated. In order to reproduce the stability of 5.7 × 10^-14 obtained by Edwards, all necessary conditions are given. The results show that when there is a larger external magnetic field, the Zeeman shift could not be neglected, so that the shield should be employed. And the design of a long cavity is advantageous to reduce the influence of the second-order Doppler effect. The results also show that at least 4-2.5℃ temperature control for cavity can effectively prevent several effects and improve the frequency stability.

| Abstract: | Frequency shifts of the acetylene saturated absorption lines at
1.5\,$\mu$m with temperature, gas pressure and laser power have been
investigated in detail. The second-order Doppler effect, the recoil
effect, the Zeeman effect, the pressure shift and the power shift
are taken into consideration. The magnitudes of those shifts caused
by various effects are evaluated. In order to reproduce the
stability of $5.7\times10^{ - 14}$ obtained by Edwards, all
necessary conditions are given. The results show that when there is
a larger external magnetic field, the Zeeman shift could not be
neglected, so that the shield should be employed. And the design of
a long cavity is advantageous to reduce the influence of the
second-order Doppler effect. The results also show that at least
$\pm $2.5\du\ temperature control for cavity can effectively prevent
several effects and improve the frequency stability. |
