Abstract:
A process to inspect bonding of a laser amplifier disc cladding comprising the steps of:forming a plate having parallel faces, said plate including a bonded first cladding;arranging a second cladding near said first cladding, said second cladding being in an inverted position relative to said first cladding to obtain an incidence perpendicular to a direction of observation;lighting an adhesive film through said first cladding and said second cladding in a direction normal relative to said parallel faces;spotting bonding defects of two glasses bonded by the adhesive film with a camera; anddigitalizing an image obtained by the camera in shades of grey so as to spot the bonding defects in the adhesive film and measure, a size of the defects.
