1·This converts it into circularly polarized light.
平行偏振光又被转化为圆偏振光。
2·Then, right-rotated circularly polarized light is the incident sample light.
入射样品光为右旋圆偏振光；
3·Then Larmor precession of the atom under the action of circularly-polarized light and outside magnetic field is analyzed.
然后，分析了原子在圆偏振光和外磁场作用下的拉莫尔进动。
