A new energy transfer chemical laser at 1.315 mu m

CW laser action has been demonstrated on the electronic I*(P-2(1/2)) --> I( P-2(3/2)) transition of atomic iodine at 1.315 mu m from the NCl (a(1)Delta ) + I(P-2(3/2)) energy transfer reaction. The stimulated emission was gener ated in a transverse subsonic flow device when hydrogen azide, HN3, was inj ected into a flow of iodine and chlorine atoms. The measured laser output p ower was 180 mW. (C) 2000 Elsevier Science B.V. All rights reserved.
