FIELD: physics. ^ SUBSTANCE: proposed laser material features garnet structure R3T5O12, where R is ions selected from the group Y, La, Ce, Gd, Sc, Lu; T is ions selected from the group Al, Ga, Sc, Lu. Laser material comprises ion of trivalent hafnium as activator. Activator concentration varies from 0.05 to 5 % by weight in terms of hafnium dioxide in excess of garnet stoichiometric formula. Said laser material can represent an optical ceramic, monocrystal or monocrystalline film. ^ EFFECT: garnet structure laser material that features high heat conductivity and resistance, long stability and can generate readjustable laser radiation. ^ 4 cl, 2 dwg |
