摘要： The invention is an apparatus and a method for drilling holes in a work piece with a laser. A laser beam is received by the optical system and directed along an optical path. The system directs the laser beam through a moveable mask aperture creating a sub-beam, that is reduced in size by a lens system as it is imaged onto a work piece. Multiple features are formed in the work piece by moving the mask.

摘要： A laser drilling system for drilling holes in a work piece with a laser. The system includes: a laser for creating a laser beam and directing the laser beam along an optical path; a mask having at least one aperture, the mask and the aperture being located in the optical path to cause the creation of a sub-beam; a lens for forming a reduced-size image of the sub-beam onto the work piece and a translation stage for moving the mask to change the position of the sub-beam on the work piece. The laser beam has a wavefront cross-section with an area greater than the size of the aperture and is incident upon the mask and the aperture to create the sub-beam.

摘要： An ultrafast laser machining system and method to form diffractive structures in optical fibers. The fiber is mounted with its longitudinal axis perpendicular to the beam path of the laser pulses. A region of the fiber is illuminated and then imaged with two cameras. These cameras are aligned substantially orthogonally. A position of the beam spot is determined. The beam spot is aligned to a starting position within the region. This position is within a portion of the fiber to be machined for which the beam path passes through the greatest length of material. The beam spot is scanned along a path designed to pass the beam spot through all of the portion to be machined such that the beam path does not pass through previously machined material. The laser pulses, which have a duration of less than about ins, are generated as the beam spot is scanned.

摘要： A method of laser machining using an ultra-fast pulse laser is presented. According to the present invention a plurality of holes with a pitch less than the wavelength of the laser are drilled into a material sample. Reliable and reproducible hole drilling is accomplished through an exemplary drilling sequence which applies a number of pulses at a first pulse energy to the surface spaced to avoid laser hardening of the surface for adjacent holes of a first set of holes. Next, the number of pulses is increased or the energy of the laser beam is increased to drill holes that are interstitial to the first set of holes. The exemplary laser machining process may used to produce both one-dimensional and two-dimensional photonic crystals, among other applications.
