Iron Fiber Laser
Abstract
We propose to investigate and demonstrate a high power fiber laser that is wavelength tunable in the 4 5 micron part of the infrared spectrum. Mid infrared light is of interest for numerous applications including medical imaging and diagnostics, remote sensing of chemicals, and infrared countermeasures against heat seeking missiles. The proposed fiber laser form is often preferred for actual applications because of its flexibility, insensitivity to vibrations and excellent thermal management. We will fabricate a chalcogenide glass –based composite material with carefully controlled refractive index profiles and softening temperatures to pull fibers of meter length or more. We will use iron ions as the active gain medium in the fiber core. An external laser will optically pump the iron ions in the core of a fiber laser device. We will demonstrate multiple watts of laser power in the 4 5 micron region, orders of magnitude greater than what is currently available.
