Method and apparatus for performing laser filamentation within transparent materials
TL;DR: In this paper, 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.

Method and apparatus for laser processing of silicon by filamentation of burst ultrafast laser pulses
TL;DR: In this paper, a laser beam is applied having at least one subpulse in a burst envelope operating at a first wavelength and the laser beam passes through a distributive lens focusing assembly and to the Kerr material.
Patent
Laser cutting strengthened glass
TL;DR: In this article, the methods for cutting strengthened glass are disclosed, which can include using a laser and an electrochromic film and can include chemically strengthened, heat strengthened, and heat tempered glass.
Patent
Laser processing of slots and holes
TL;DR: In this paper, a process for cutting and separating interior contours in thin substrates of transparent materials, in particular glass, is described. But the method involves the utilization of an ultra-short pulse laser to form perforation or holes in the substrate, that may be followed by use of a CO2 laser beam to promote full separation about the perforated line.
Patent
Method and apparatus for spiral cutting a glass tube using filamentation by burst ultrafast laser pulses
TL;DR: In this paper, a spiral cut transparent tube using laser machining is presented, where a beam waist is formed external to the surface of the transparent tube, where the laser pulses and sufficient energy density are maintained within the tube to form a continuous laser filament therethrough without causing optical breakdown.

Observation of Self-Phase Modulation and Small-Scale Filaments in Crystals and Glasses
Robert R. Alfano,S. L. Shapiro +1 more
TL;DR: In this paper, small-scale filaments were observed in calcite, quartz, sodium chloride, and several glasses under picosecond pulse excitation, and the physical mechanism responsible for these processes is the change in refractive index resulting from electronic distortion.
Patent
Electrochromic mirrors and devices
TL;DR: In this paper, the present invention relates to electrochromic mirrors and devices whose electro-chromic element is composed of an electro chromic solid film and an electrolyte comprising redox reaction promoters and alkali ions and/or protons.

Method for controlling configuration of laser induced breakdown and ablation
Gerard Mourou,D. Du,Subrata Dutta,Victor M. Elner,Ron M. Kurtz,Paul R. Lichter,Xinbing Liu,P.P. Pronko,Jeff Squier +8 more
TL;DR: In this article, the authors proposed a method for laser induced breakdown of a material with a pulsed laser beam where the material is characterized by a relationship of fluence breakdown threshold (Fth) versus laser beam pulse width (T) that exhibits an abrupt, rapid, and distinct change or at least a clearly detectable change in slope at a predetermined laser pulse width value.
Patent
Laser processing method and laser processing apparatus
TL;DR: In this article, the authors present a method for cutting a work without producing a fusing and a cracking out of a predetermined cutting line on the surface of the work, where a pulse laser beam is radiated on the predetermined cut line, and a modified area is formed inside the work along the determined cut line by moving the condensed point along the predetermined cutoff point, whereby the work can be cut with a rather small force by starting from the modified area.
