Long operating time CW atomic iodine probe laser at 1.315 microns
Abstract
A photolytically pumped longitudinal flow CW atomic iodine laser at 1.315 microns with virtually an unlimited operating time and easy operation is reported. Several weeks of continual operation is easily attainable. The prolonged lasing is achieved by employing a passive closed cycle flow system of the C3F7I laser fuel. A high pressure dc Hg arc lamp is used for the photolytic pumping. Peak CW powers of 38 mW have been obtained along with good stability (approximately 1 percent amplitude fluctuations) in the fundamental TEM(00) mode via the use of an internal lens.
