  • Patent number: 9625713
    Abstract: A method for the laser reinforced direct bonding of two optical components having a respective bonding surface and a reinforced optical assembly made thereby are provided. The method includes a first step of assembling the two optical components by direct bonding of their respective bonding surface together, thereby defining a direct-bonded interface therebetween. The method further includes a second step of reinforcing the direct-bonded interface with a weld seam including at least one substantially continuous reinforcing weld line forming a closed shape enclosing a sealed direct-bonded region. Each weld line is inscribed by focusing ultrashort laser pulses at the direct-bonding interface so as to generate non-linear optical phenomena inducing a localized junction between the two optical components.

The method includes a first step of assembling the two optical components by direct bonding of their respective bonding surface together, thereby defining a direct-bonded interface therebetween. The method further includes a second step of reinforcing the direct-bonded interface with a weld seam including at least one substantially continuous reinforcing weld line forming a dosed shape enclosing a sealed direct-bonded region. Each weld line is inscribed by focusing ultrashort laser pulses at the direct-bonding interface so as to generate non-linear optical phenomena inducing a localized junction between the two optical components.
