Copper(II) bromide (CuBr2) is a chemical compound. It is used in photographic processing as an intensifier and as a brominating agent [1] in organic synthesis [1]

It is also used in the Copper vapor laser, a class of laser where the medium is copper bromide vapour formed in situ from hydrogen bromide in reaction with the enclosing copper discharge tube. [2] Producing yellow or green light, it is used in dermatological applications.
