Co_2 Laser의 開發에 關한 硏究 = Construction of CO_2 Laser

다국어 초록 (Multilingual Abstract)

Gas flowing type CO_2 Lases of intermediate power were designed and constructed with domestic materials. A typical Laser has 140㎝ optical cavity distance and 20㎜ discharge tube cross section.
Two internally mounted cavity mirrors were concave of 500㎝ radii and coated with many layers of pure gold and copper alternatively by means of sputtering and evaporation technique in this laboratory.
The reflectivity of mirrors for the 10.6 micron IR schowed nearly 96 percent which indicates they were perfectly suitable for CO_2 Laser.
The reliability of all Laser materials and gas injection were examined at various conditions such as the gas pressure, mixing ratio of gases, and the exciation currents and found to be satisfactory.
For an optimum condition, the output of Laser was estimated about the order of 30 watts. This implies that further improvement of lasing action will attain more powerfull Laser beam.
