Abstract

CO₂ lasers emit laser lines at about 90 discrete wavelengths around 10 micrometer. A blazed grating is usually employed as the output mirror in the resonator. By adjusting the angle between the grating and the optical axis, a desired laser line can be selected since all other potential laser lines will suffer from high losses. For the purpose of increasing the laser lines so as to broaden its pumping ability for far infrared lasers, the dependence of lasing lines on the components as well as the total pressure has been investigated. The laser envelope used was 1200 mm long with a capillary diameter 12 mm. Lasing lines was in situ measured by using Wang's method. Experimental results will be reported in the manuscript.
