The variational problem of the optimal operating conditions in the gasdynamic carbon dioxide laser is solved in such a way as to maximize the gain for the P20(001) $Yields$ (100) transition in the case of nozzles of arbitrary shape. A comparison is made with the results of optimization obtained for planar wedge-shaped nozzles. The optimal initial conditions (temperature, pressure, and composition) are found and the optimal nozzle shape is obtained for mixtures of carbon dioxide with nitrogen and helium. A continuous increase in the gain with rising pressure is predicted for optimal operation of the gasdynamic laser. (AIP)
