An Annular Iodine Laser Facility.
Abstract
The design and performance of an annular iodine laser built to study annular resonators at a large Fresnel number are described. A high-intensity axial flashlamp is used to dissociate C3F7I vapor in the annular lasing region. The excited iodine atoms resulting from this dissociation produce radiation of 1.315 micrometer wavelength by stimulated transition to the ground state. The pulsed energy output of 12.5 J was close to the performance estimates, which also indicated a small signal gain of 6.2 per meter, required for saturation of the medium, could be obtained. The details of the high-voltage capacitor discharge circuit, the vacuum and gas handling system, and the laser tube fabrication are described. (Author)
