    Abstract: Systems, devices, and methods including a modified Herriot cell (100) comprising: a laser (108) configured to generate a single beam (115); a partially transmissive facet (PTF) (112) disposed in at least one of: a first mirror (102) and a second mirror (104), where a first portion of the single beam is received through the PTF, and wherein a second portion of the single beam is reflected by the PTF; a first detector (106a) disposed proximate the PTF, wherein the first detector receives the first portion of the beam, and where the first portion of the beam has traveled a first path length (126) from the laser to the first detector; and a second detector (106b) disposed proximate the exit hole, where the second detector receives the second portion of the beam, and wherein the second portion of the beam has traveled a second path length (128) from the laser to the second detector.
