Different geometry nozzles used in CW Hydrogen Fluoride chemical laser are investigated. Four geometry parameters, including throat width, area ratio, axis length and base width, are considered. The flow properties, laser outcoupling power and small signal gain (SSG) of a Fabry-Perot resonator are calculated. The results show that when throat width and area ratio increase, the power and SSG peak will decrease in varying degree; they also varied when axis length changed; larger base width is related to lower cavity pressure, and smaller base width is related higher cavity pressure.
