A VERSATILE EIGHT-METER GAS LASER SYSTEM.
Abstract
An 8-meter-long, versatile gas laser and associated equipment were designed and constructed, employing three methods of excitation (60-c/s ac, dc, and rf) and a Brewster-angle prism method of intracavity wavelength selection. The high gain resulting from the extreme length of the laser facilitated the finding of previously unreported laser lines in the infrared. A novel method of facilitating the alignment of mirrors, making use of the 3.39-micron He-Ne line, was utilized. Calculations of reflectance for light polarized parallel to the plane on incidence for small deviations from the Brewster angle are give for an air-quartz interface. (Author)
