The Los Alamos Free Electron Laser (FEL) Facility has been in operation as an oscillator in the 10 μm wavelength regime since 1983. Operations from 10 to 45 μm have been recently demonstrated which would provide a new applications capability: a Mid- Infra red Adjustable Coherent Light Experiment (MIRACLE) Facility. We propose to extend this tunability from 3 to 160 μm by upgrading the injector, accelerator, and resonator cavity. Potential applications in material science (high-temperature superconductors) and biophysics (DNA spectroscopy) for this wavelength regime are briefly addressed.
