Abstract:
The light source includes a high-efficiency solid-state laser source emitting excitation coherent radiation, and a single crystal phosphor forming an optic element for receiving the excitation coherent radiation and emitting light with desired parameters. The single crystal phosphor is made of garnets conforming to the general formula (Ax,Lu1-x)aAlbO12:Cec formula, or from a single crystal material of perovskite structure conforming to the general formula B1-gAlO3:Dq.
