1. Bulk materials having a plurality of kinetically limited nano-scale diffusion bonds and comprising:
a transparent material having properties that allow an electromagnetic beam of a select wavelength to pass there through without more than minimal energy absorption;
an absorbent opaque material having properties that significantly absorb energy from the electromagnetic beam; and
an interfacial bond joint comprising a patterned diffusion bond formed by the electromagnetic beam bonding the transparent material to the absorbent opaque material, wherein the patterned diffusion bond comprises first and second kinetically limited nano-scale diffusion bonds spaced apart by at least one unbonded area proximately located between the first and second kinetically limited nano-scale diffusion bonds,
the diffusion bonds including an interfacial bond joint region and an amorphous diffusion zone within the interfacial bond joint region, and
wherein the bulk materials comprise undisturbed transparent material and undisturbed absorbent opaque material proximately located on opposing sides of the interfacial bond joint, and the undisturbed transparent material or the undisturbed absorbent opaque material has mechanical properties or chemical resistance that are not degraded by the patterned diffusion bond.
