Lasing on the B..-->..X bands of CdI at 655 nm and CdBr at 811 nm has been obtained by photodissociating CdI/sub 2/ and CdBr/sub 2/ with an ArF laser. Also, the CdX (X = I, Br) B-state radiative lifetimes and CdX/sub 2/ quenching rate constants were found to be 32 +- 3 ns, (9.2 +- 1.1) x 10/sup -10/ cm/sup 3/ s/sup -1/, 25 +- 4 ns and (7.9 +- 3.3) x 10/sup -10/ cm/sup 3/ s/sup -1/, respectively. After synthesizing and photodissociating /sup 114/CdI/sub 2/, the /sup 114/CdI laser spectrum was identified as arising from v' = 0-2..-->..v'' = 61, 62 transitions of the B..-->..X band. The use of a single isotope of Cd (i.e., /sup 114/Cd) was also found to quadruple the energy output of the CdI laser and to make possible a dual-wavelength metal-halide laser, one operating simultaneously in the red (CdI) and near-infrared (CdBr).
