Effects of passive isolation on several optically pumped far-infrared laser lines
Abstract
The effects of a passive isolation technique on several well-known FIR laser lines have been investigated experimentally using an isolator consisting of a combination of a polarizer and a quarter-wave plate inserted between the pump and the FIR cavities in a longitudinally pumped system. In addition to enhancing the output power stability, this isolation scheme is shown to result in increased pump-to-FIR power-conversion efficiency.
