A method of forming a strengthened glass article is provided. The method includes providing a strengthened glass article. The strengthened glass article is in the form of a container including a sidewall having an exterior surface and an interior surface that encloses an interior volume. The sidewall has an exterior strengthened surface layer that includes the exterior surface, an interior strengthened surface layer that includes the interior surface and a central layer between the exterior strengthened surface layer and the interior strengthened surface layer that is under a tensile stress. A laser-induced intended line of separation is formed in the central layer at a predetermined depth between the exterior strengthened surface layer and the interior strengthened surface layer by irradiating the sidewall with a laser without separating the glass article.

With a method of cutting a tube glass (G1) according to the present invention, the tube glass (G1) is irradiated with laser light (L) having a focal point (F) adjusted to an inside of the tube glass (G1), to thereby form an inner crack region (C1) including one or more cracks in a portion of the tube glass (G1) in a circumferential direction of the tube glass (G1) through multiphoton absorption that occurs in an irradiation region of the laser light (L). Then, in the tube glass (G1), there is generated a stress that urges the one or more cracks in the inner crack region (C1) to propagate in the circumferential direction of the tube glass (G1) to cause the one or more cracks to propagate throughout an entire circumference of the tube glass (G1), to thereby cut the tube glass (G1).
