Dissociation of Molecular Iodine During Mixing With Singlet Oxygen Flow

“…In the typical COIL conditions the iodine molecular diffision coefficient is D=(l-2)102 cm2s-1 [4] and the characteristic diffusion time ~~=L2/D=(l-5)10-3~ where L=0.5-1 cm is a typical distance between the holes through which iodine is injected. Since tdf is sufficiently greater than tds the iodine dissociation will proceed in highly inhomogeneous conditions and the gain will strongly vary across the SO flow depending on the distance from the place of the iodine injection [6].…”
