“…Therefore, the sol prepared in “ Preparation of colloidal silica sol ” section was spin-coated over KDP crystals (50 mm × 50 mm × 10 mm) under a velocity of about 300 rpm at a rated time of 80 s to modulate the coating thickness to the designed value (~ 70 nm) 17 20 . The test results of coating thickness and laser damage threshold can be found in literature 14 . The resulting coating was used as reference (named as coating A).…”

“…In summary, this type of laser coating damage is noticed recently and found very harmful for the transmission and lifetime of KDP/DKDP component, but studies aimed at this specific coating failure can be hardly found. In our previous work 14 , a series of structural changes in the coating damage process was analyzed, including the adhesion changes of the interface layer. It was found that the conversion behavior of Si–O–Si to Si–O–K at the interface during the damage process led to the enhancement of adhesion of the coating, which was very crucial to the coating damage.…”
