1. A spectroscopy system, comprising:
a cell having a plurality of walls and forming a chamber therein, the chamber being configured to receive at least one laser signal and retaining a vapor therein, the vapor fluorescing in response to the at least one laser signal;
a photodiode; and
a plurality of mirrors configured to direct fluorescent light from the vapor toward the photodiode;
wherein the chamber has a length in a direction of propagation of the at least one laser signal not exceeding ten millimeters.
