The character of surface optical breakdown is connected with intrinsic and induced defects. The methods and instruments of scanning near-field optical microscopy (SNOM) were applied for its investigation. The methods of SNOM allowed receiving full information about local optical properties and microstructure of the surface, and distribution of the light field over the surface. Evolution of the surface defects under powerful fields can be studied with SNOM as well. The basic principles of application of SNOM to investigation of surface optical breakdown of transparent dielectrics were described.
