Mixed lanthanide aluminates - magnesium, lasers using the single crystals of these aluminates. / p & & p & these lasers are in particular two flash lamp 18, 20 to be pumped longitudinally a bar 16 of a monocrystalline aluminate magnetoplumbite type of application emitting a visible or infrared amplified between a mirror 26, 28, a prism polarizer 30 serving to send it towards the outside of the laser light beam amplifies. The aluminate present the following formula: (la1 - xtr) 1 -, - vmg1 - z - tal11 - uy2z3cro19 - t - 3v2dans which r represents: a.au least one trivalent simple compound chosen from among the lanthanides, y3, sc3, or b.aumoins a pair of lanthanides the form of an element of a divalent and trivalent element, with the electrical neutrality by the addition of aluminum or of oxygen vacancies, or any combination of a and b; x is a number such that 0 x 1, y and v are numbers such that 0 v 0,4 y, z and t are numbers such that 0 z, t 1 is a condition that, when z t 0, v 0 to tr representing one trivalent lanthanide; u is an integer ranging from 0 to 2 is a condition that, when r represents y3 and sc3, u or 0, that, when x 0, u or 0, and when u 0, x is 0.
