Abstract: Here we summarize our progress in the development of 2- to 5-micron wavelength supercontinuum sources through grant number FA8650-05-C-5426 over the life of the program. The key developments over the past 3 years include 1) A proof-of-principle demonstration of a novel, efficient mid-IR Raman laser source in silica materials system, yielding efficient spectral transfer to 2.41 microns. (The demonstrated system can be naturally extended in wavelength to 5microns and beyond); 2) The development of nonlinear-optical simulation capabilities; 3) Progress toward the development of low loss, highly nonlinear chalcogenide fibers; 4) Novel interferometric measurement techniques to examine the integrity and loss mechanisms of such fibers; and 5) Nonlinear studies of chalcogenide fibers and prospects for extending our cascaded Raman source to longer wavelengths.
