Abstract
Abstract The invention relates to a novel oxide for tunable lasers. These oxides comply with the formula: (A1-xXx)n(B1-yYy)mO4 in which A represents one or more elements chosen from the group Mg, Mn and Zn; X represents one or more optically active divalent cations chosen from among V, Ni and Co; B represents one or more elements of the same valence chosen in the group comprising Si, Ge, P, Te, W, Al, In, Ga and Mo; Y represents one or more optically active trivalent cations chosen from among Cr, V and Ni; x is such that 0</=x</=0.15; y is such that 0</=y</=0.15; and m and n are integers such that 2n+vm=8 with v representing the valence of B, provided that y=0 when B represents one or more elements chosen from among Si, Ge, P, Te, W and Mo and x and y are not both equal to 0. As an example of such oxides, reference is made to Mg0.99Ni0.01Al2O4 whose absorption spectrum (continuous lines) and emission spectrum (broken lines) are given in the attached drawing.
