Zeeman interferometry, based on the two-frequency Zeeman effect laser, can be used for simple, noncontact differential thermometry. The thermometry is differential in both space and time. Small (0.73 μl ) laser-heated volumes were monitored with a Zeeman interferometer. Heating rates varied over six orders of magnitude from 180 μK/s to 330 K/s. Temporal resolution was 10 μs. Measured temperatures and measured rates of heating were compared with theory for slowly and rapidly heated samples, respectively.

    The splitting of levels of the 1s5g and 1s6g configurations of the helium atom in an external magnetic field (0-160 Oe) is obtained by using the fine-structure parameters calculated semiempirically. For each configuration, more than 50 crossings and three anticrossings of Zeeman sublevels are...
