Carbon Composite Reinforcement For Waterfront Construction

Not Available Lasers operating in the mid-infrared (MIR) spectral region have overwhelming importance to commercial, space and military applications such as remote sensing/measurement of atmospheric aerosols, clouds, molecular species and meteorological parameters. Brimrose Corporation, in collaboration with Dr. Uwe Hommerich at Hampton University, has developed a novel; tunable room temperature solid-state laser material using transition metal doped Cd1-xMnxTe {1-10}. We have obtained room temperature lasing in Cr:Cd1-xMnxTe and we have seen low temperature luminescence in Co:Cd1-xMnxTe indicating its potential for use as a mid-infrared laser medium. During the proposed work, we will focus our efforts on developing materials for room temperature mid-infrared lasing, and we will fabricate a prototype room temperature, solid-state, tunable mid-IR laser. We will continue our investigation of Cr: Cd0.55Mn0.45Te and optimize this material for improved mid-infrared laser performance; and we will investigate the material system cobalt doped Zn1-xMnxTe for room temperature mid-infrared lasing. Based on prior work [11-14], we believe that Co:Zn1-xMnxTe has an excellent potential for exhibiting room temperature mid-infrared lasing up to 4um. During Phase I, we will concentrate our efforts on optimization of the laser materials and we will fabricate a prototype room temperature, mid-IR tunable solid-state laser system.
