Optical Spectroscopy of Rare-Earth doped Halides for Mid-IR Laser Applications
About the Research
New gain media for mid-infrared (MIR) solid-state laser are currently being developed through research in finding host materials that have good optical, mechanical, and thermal properties to withstand the operating conditions of practical lasers. These MIR transitions, however, are strongly quenched due to non-radiative decay in traditional laser hosts based on oxide and certain fluoride crystals. In order to overcome the strong emission quenching, new laser hosts with low maximum phonon energies are currently being sought for direct MIR lasers. The Army Research Laboratory's Advanced Solid-State Lasers Team is involved in enabling technology for high-energy pulsed mid-IR lasers development. Research tasks include material processing, spectroscopic studies on absorption,
