Laser engraving
is the process of removing material from a surface using laser light, either through ablation or vaporisation. Suitable for many different metals and coated metals.

Laser etching
is basically the same as above however usually refers to glass or lithographic plates
 

Laser marking
involves using laser light to change the surface of a substrate, either through burning or altering the chemical composition of the substrate. Usually used for part marking, inventory control etc. Generally only suitable for some plastics, however exceptions apply.   Laser marking sometimes also refers to pre or post-processed items eg oxidised brass. Note some engravers claim to be engraving metal whey they are really marking metal.
 

Laser annealing (also known as Surgical Blackening)
is a process similar to laser marking where very little/no material is removed but the surface colour is changed through extreme heat exchange in a very small area. Laser annealing leaves a rainbow/grey or black  mark. Suitable for stainless steel and some other metals it is usually used in the marking of sensitive instruments where an unblemished & smooth surface is essential.
