Abstract

New methods for laser material processing in optically transparent materials are described using the volume optical breakdown phenomenon. This occurs when ultra-short pulses of the order of tens of picoseconds or less, are focused into the volume of the material by means of a high quality focusing objective lens. A focal spot close to the diffraction limit for the laser wavelength is obtained within the material. A number of processing techniques are described which are impossible to perform with hitherto available methods, including ultra-fine hole drilling, ultra-fine cutting processes, ultra-fine resolution marking or image formation applied to the interior of a sample, including diamonds, and the formation of deep black images in plastic materials.
