Refractive index detector using Zeeman interferometry
- Los Alamos National Laboratory, Los Alamos, New Mexico 87545 (US)
We discuss the theory and error analysis for an ultrasensitive refractive index detector based on the two-frequency Zeeman effect laser. Experimental measurements on gases agree fairly well with predictions. With a 5-cm pathlength, the typical interferometry stability is {Delta}{ital n}=8{times}10{sup {minus}9}/h. Resolution is {Delta}{ital n}=1{times}10{sup {minus}9}.
