Abstract
Methods for bonding transparent materials to opaque materials. The materials to be bonded are placed in tightly abutting relation to one another, and an energetic laser pulse is directed through the transparent material until it melts a thin surface layer of the opaque material. The desired bond is formed when the melted layer solidifies. In alternative embodiments the transparent material is precoated with various mediator materials to facilitate the bonding process.
