In an earlier publication,1 we reported the theoretical gain optimiation studies of a 16-\mu m $CO_2-N_2-H_2$ gasdynamic laser (GDL) in which it was showed that the optimum value of a 2.06% $cm^{-1}$ gain could be obtained with conical or hyperbolic nozzles. In this Note, we report the results of optimization studies with a 16\mu m $CO_2-N_2-H_2$ GDL using twodimensional wedge nozzles. We have found that the optimum value of the gain that can be achieved is as high as 12.7% $cm^{-1}$ on the P(15) line of the $(02^00)$\rightarrow $(01^10)$ transition of $CO_2$ for a gas mixture composition of $CO_2:N_2:H_2$ =30:50:20%. The corresponding optimum values for the reservoir pressure and area ratio are computed as functions of the resevoir temperature and presented graphically. Results are presented for a range of gas mixture compositions.
