The machines for laser engraving and laser marking are the same, so the two terms are sometimes confused by those without relevant expertise. The impact of laser marking has been more pronounced for specially designed "laserable" materials and also for some paints. These include laser-sensitive polymers and novel metal alloys. [2]
Laser bonding is a marking technique that uses lasers to bond an additive marking substance to a substrate.. First invented in the mid 1990s by Essilor International, this patented method [1] produces permanent marks on metal, glass, ceramic and plastic parts for a diverse range of industrial and artistic applications, ranging from aerospace and medical to the awards and engraving industries.
Marking blue or layout stain (sometimes called Dykem after trademark erosion of a popular brand, or Prussian blue after the blue pigment) is a dye used in metalworking to aid in marking out rough parts for further machining.
Engineer's blue is prepared by mixing Prussian blue with a non-drying oily material (for example, grease).The coloured oil is rubbed onto a reference surface, and the workpiece is then rubbed against the coloured reference; the transfer (by contact) of the pigment indicates the position of high spots on the workpiece or conversely highlight low points.

Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
A laser designator is a laser light source which is used to designate a target. Laser designators provide targeting for laser-guided bombs , missiles , or precision artillery munitions, such as the Paveway series of bombs, AGM-114 Hellfire , or the M712 Copperhead round, respectively.
