Two stage laser stabilization using external cavities: Application to a 10 μm CO2 laser locked to an OsO4 transition
Abstract
A cw carbon dioxide laser, operating on the 10 μm R(0) transition (28.832 THz), was stabilized by locking its frequency to an evacuated Fabry-Pérot cavity. The Fabry-Pérot cavity was in turn stabilized to the saturated absorption resonance of the Q(15) line of 188OsO4 , contained in a second Fabry-Pérot cavity. Cesium-clock referenced, frequency chain measurements of the resultant line frequency are presented together with detailed studies of the line shift sensitivities to various operating parameters.
