Abstract
Mixed lanthanide-magnesium gallates and laser using monocrystals of these gallates. This laser has two flash lamps for longitudinally pumping a monocrystalline rod of a magnetoplumbite-type gallate emitting a light ranging from the UV to the IR, which is amplified between two mirrors and a polarizing prism serving to pass to the outside of the laser the amplified light beam. The gallate is of formula: ##STR1## in which M.sup.1 represents Nd, Pr, Ce, Nd-Ce or Pr-Ce in the trivalent state; M.sup.2 represents aluminium, optionally partly substituted by scandium and/or indium; k is a number between 0.94 and 1; x is a number between 0 and 1; t is a number such that 0.ltoreq.t.ltoreq.0.05, provided that t is.noteq.0 when x=0 and that x is .noteq.0 when t=0; v is a number such that 0.ltoreq.v+t<1 and z is a number between 0 and 0.5.
