Abstract : This invention relates generally to producing impurity concentration profiles in solids and particularly to methods of producing semiconductor devices and optical waveguides. An impurity concentration profile is established in a solid by attaching the solid to heat sink and irradiating it with one or more fast laser pulses. The impurity may initially be located in a surface layer or it may be dispersed throughout the solid.
