This aberration range is not less than n×d and not more than n×d+Δs from an incidence plane of the medium 60, provided that the refractive index of the medium 60 is defined as n, a depth from an incidence plane of the medium 60 to the focus of the lens 50 is defined as d, and aberration caused by the medium 60 is defined as Δs.

摘要： Systems and processes of cutting and drilling in a target substrate uses a laser (e.g., a pulsed laser) and an optical system to generate a line focus of the laser beam within the target substrate, such as a glass substrate sheet, are provided. The laser cutting and drilling system and process creates holes or defects that, in certain embodiments, extend the full depth of the glass sheet with each individual laser pulse, and allows the laser system to cut and separate the target substrate into any desired contour by creating a series of perforations that form a contour or desired part shape. Since a glass substrate sheet is brittle, cracking will then follow the perforated contour, allowing the glass substrate sheet to separate into any required shape defined by the perforations.

摘要： Systems and methods are described for forming continuous laser filaments in transparent materials. A burst of ultrafast laser pulses is focused such that a beam waist is formed external to the material being processed without forming an external plasma channel, while a sufficient energy density is formed within an extended region within the material to support the formation of a continuous filament, without causing optical breakdown within the material. Filaments formed according to this method may exhibit lengths exceeding 10 mm. In some embodiments, an aberrated optical focusing element is employed to produce an external beam waist while producing distributed focusing of the incident beam within the material. Various systems are described that facilitate the formation of filament arrays within transparent substrates for cleaving/singulation and/or marking. Optical monitoring of the filaments may be employed to provide feedback to facilitate active control of the process.
