Interrelation between the Optical and Mechanical Strengths of Composites with Sol Coatings

Resumo

We consider the interrelation between the optical and mechanical strengths of glass composites with coatings obtained using sol–gel technology. The threshold energy density of a nanosecond laser pulse is connected to the microhardness of the composite, its reflection coefficient at the working laser wavelength, and coating thickness; the threshold energy density of a microsecond laser pulse decreases with increasing microhardness of the composite and film thickness.
