Glass properties and applications

Theoretical interpretation of damage formation in coated optical glasses is given and its low damage threshold is found to be due to the energy confinement in a narrow gap between the glass substrate and the coated material. The experiments supporting this mechanism are conducted with noncoated, hard-coated, and porous-coated glasses.
