Abstract
A compound or complex containing a rare earth element is impinged with a pulsed laser that is so controlled as to photochemically reduce and obtain a rare earth metal (REM). A mixture of REM salts can be impinged using laser light tuned to selectively reduce a particular rare earth-containing salt of the mixture to separate out as its respective rare earth metal.
