Paper Abstract

Optical amplification of a mid-IR laser using a Co2+ :CdTe amplifier was attempted by a double-pass technique. A 2.825 μm pump source was used to amplify a 3.780 μm seed source through the gain medium. Of transition-metal-doped chalcogenide lasers, iron (Fe2+) and chromium (Cr2+) have emerged as practical sources of tunable mid-infrared radiation, while cobalt (Co2+) still remains comparatively unexplored. The initial observations of directly pumping into the 4T2 energy level are reported and discussed to better understand the potential of Co:CdTe as a mid-infrared gain medium.
