摘要：

Modified GaSe single crystal was grown from the melt with charge composition GaSe + 10 mass% of AgGaSe2. Lattice structure, visible to mid-IR and further THz range optical properties, as well as Raman spectra were studied in details. The grown crystal was identified as epsilon-GaSe:Ag (0.04 mass%). This silver content in GaSe has resulted in 6% decreased non-linearity that was over compensated in CO2 laser SHG efficiency by vanished of bulk damages and 10-20% improved surface damage threshold. About 30% increased microhardness is promising for cut and polishing at arbitrary direction and epsilon-GaSe:Ag applications in out-of-door systems. (C) 2012 Elsevier B.V. All rights reserved.
