Optically-pumped laser action in monodeutero-acetylene (HCCD)
Abstract
Optically-pumped laser action has been observed in HCCD on 15 new lines between 464.8 and 564.8 cm -1, using 8 pump lines in the CO 2 laser 9 μm band. Maximum output energies of 120 mJ have been obtained with 5 J pump energy. The pump transitions are mainly to 2 ν4, with some hot-band and Δl forbidden pump transitions also being observed. Parametric studies of the lasers' performance as a function of pressure and temperature are presented.
