AbstractA practical study has been carried out on axial flow CW CO2 laser by
changing the output coupler with a wide range of reflectivities. ZnSe mirrors
were used in various reflectivities (20, 30, 40, 45, 50, 55, 60, 65, 70,75,80,85,90).
It has been found that the output power varies considerably with varies the
reflectivity of the output coupler. Thus the optimum reflectivity for 1m
optical length and 1cm discharge tube of CW CO2 laser is found to be 65±
5%. Our results have been compared with other published data.
