Nozzle tip manufacturing

A method of forming a nozzle tip 102 of a fuel injector nozzle in which firstly a hole forming step takes place. The holes 106 are formed by laser drilling and extend through the wall section 104 and partly into a blank of material 130 within the nozzle tip. Secondly, a subsequent sac-forming step is carried out, comprising removing the blank 130 to form a sac (Fig 5, 108). The laser drilling may be controlled so that the laser can be applied for a predetermined time period or until a predetermined amount of energy is expended. This method therefore avoids the requirement for sacrificial inserts to avoid damage by impinging of the laser beam upon internal surface of the nozzle tip and/or adherence of melted particles to the internal surface.

A system for laser processing a transparent material

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 up to 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.
