Sub-surface laser engraving is the process of engraving an image in a transparent solid material by focusing a laser below the surface to create small fractures. Such engraved materials are of high-grade optical quality (suitable for lenses, with low dispersion) to minimize distortion of the beam.
Bubblegram. A laser glass sculpture of a caffeine molecule. A bubblegram (also known as laser crystal, Subsurface Laser Engraving, 3D crystal engraving or vitrography) is a solid block of glass or transparent plastic that has been exposed to laser beams to generate three-dimensional designs inside. The image is composed of many small points of ...
In science, lasers are used in many ways, including: A wide variety of interferometric techniques. Raman spectroscopy. Laser induced breakdown spectroscopy. Atmospheric remote sensing. Investigating nonlinear optics phenomena. Holographic techniques employing lasers also contribute to a number of measurement techniques.
Laser engraving has also been making headway in the wedding invitation market over the last few years. Primarily used for engraving wood veneer invitations, it is also used to engrave acrylic or to mark certain types of metal invitations. The latest trend in wedding invitations is to order them online.
Laser cutting. Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics.
Engraved glass is a type of decorated glass that involves shallowly engraving the surface of a glass object, either by holding it against a rotating wheel, or manipulating a "diamond point" in the style of an engraving burin. It is a subgroup of glass art, which refers to all artistic glass, much of it made by "hot" techniques such as moulding ...
Rotogravure (or gravure for short) is a type of intaglio printing process, which involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, it uses a rotary printing press. Once a staple of newspaper photo features, the rotogravure process is ...
Color Laser Engraving is a marking process that uses MOPA fiber laser source to mark color on metal surface such as stainless steel, titanium, etc. MOPA refers to a configuration consisting of a master laser (or seed laser) and an optical amplifier to boost the output power. A special case is the master oscillator fiber amplifier (MOFA), where ...
