Glass articles with protective films and methods of forming glass articles with protective films

A method of producing a glass blank, comprising:

• cutting a glass sheet via a pulsed laser beam focused into a quasi-non-diffracting beam, wherein the glass sheet comprises a first surface, a second surface opposing the first surface, an edge surface connecting the first surface and the second surface, a first coating disposed on the first surface of the glass sheet, and a second coating disposed on the second surface of the glass sheet, wherein the laser beam is directed into a stack comprising the first coating, the glass sheet, and the second coating, wherein the quasi-non-diffracting beam enters the stack and generates an induced absorption within the stack, wherein the induced absorption produces a damage track defining the glass blank within the first coating at the first surface, the glass sheet, and the second coating at the second surface, wherein the first coating and the second coating is transparent to at least one wavelength of the pulsed laser beam;
• removing a portion of the first coating from the glass sheet;
• removing a portion of the second coating from the glass sheet;
• and
• separating the coated portion of the glass sheet to form the glass blank from the uncoated portion of the glass sheet.

A method of producing a glass blank, comprising:

• directing a pulsed laser beam, focused into a quasi-non-diffracting beam, into a glass sheet, wherein the glass sheet comprises a first surface, a second surface opposing the first surface, an edge surface connecting the first surface and the second surface, a first coating disposed on the first surface of the glass sheet, and a second coating disposed on the second surface of the glass sheet, wherein the quasi-non-diffracting beam generates an induced absorption to produce a first damage track within the first coating;
• removing a portion of the first coating defined by the first damage track from the first surface;
• directing the pulsed laser beam, focused into the quasi-non-diffracting beam, into the second coating, wherein the quasi-non-diffracting beam generates an induced absorption to produce a second damage track within the second coating at the second surface;
• removing a portion of the second coating defined by the second damage track from the second surface;
• directing the pulsed laser beam, focused into the quasi-non-diffracting beam, into the portion of the glass sheet without the first coating and the second coating, wherein the quasi-non-diffracting beam generates an induced absorption within the glass sheet to produce a third damage track within the glass sheet;
• and
• separating the glass blank from the glass sheet.

A method of producing a glass article, comprising:

• directing a pulsed laser beam, focused into a quasi-non-diffracting beam, into a glass sheet, wherein the glass sheet comprises a first surface, a second surface opposing the first surface, an edge surface connecting the first surface and the second surface, a first coating disposed on the first surface of the glass sheet, and a second coating disposed on the second surface of the glass sheet , wherein the quasi-non-diffracting beam generates an induced absorption to produce a first damage track within the first coating at the first surface;
• removing a portion of the first coating defined by the first damage track from the first surface;
• directing the pulsed laser beam, focused into the quasi-non-diffracting beam, into the portion of the glass sheet without the first coating, wherein the quasi-non-diffracting beam generates an induced absorption within the glass sheet to produce a second damage track within the glass sheet;
• directing the pulsed laser beam, focused into the quasi-non-diffracting beam, into the second coating, wherein the quasi-non-diffracting beam generates an induced absorption to produce a third damage track within the second coating at the second surface;
• removing a portion of the second coating defined by the second damage track from the second surface;
• and
• separating the glass blank from the glass sheet.

• and
• separating the glass blank from the glass sheet.

A method of cutting a glass article, comprising:

• directing a laser beam into a first surface of a glass sheet to produce a damage track within the glass sheet, wherein the first surface is a flat surface and wherein the glass sheet further comprises:
• a second surface opposing the first surface, wherein the second surface is a structured surface, a protective coating disposed on the second surface, the protective coating having a refractive index greater than or equal to a refractive index of the glass sheet;
• guiding the laser beam over the glass sheet to define the glass article;
• and
• separating the glass article from the glass sheet.
