在铯原子气室磁光阱 (ＶＣ -ＭＯＴ)及超高真空磁光阱 (ＵＨＶ -ＭＯＴ)实验中 ,需要将冷却和俘获激光负失谐锁定于铯原子Ｄ2 线的 6 2 Ｓ1/2 Ｆ =4→ 6 2 Ｐ3 /2 Ｆ′ =5超精细跃迁线处。以此为目的 ,我们以光栅外腔式主振荡器—功率放大型 (ＭＯＰＡ)半导体激光器作为光源 ,
In the cesium-atom VCMOT and UHV-MOOT experiments, the cooling and trapping laser negative-anharmonic locked to the 6 2 S1 / 2 F = 4 → 6 2 P3 / 2 F ’= 5 Hyperfine transition line at. For this purpose, we grating external cavity main oscillator - power amplifier (MOPA) semiconductor laser as a light source,
