There are two distinct laser cleaning processes; coating removal and surface decontamination. The former is characterized by removing a layer of unwanted material from the surface of a substrate. It is most effective when the physical and chemical composition of the layer differs from the substrate. Such include insulation, primers, corrosion preventive coatings, rubber or paint. The latter involves removing the entire upper layer of the substrate and requires high flux laser beams.
A laser can be classified as operating in either continuous or pulsed mode, depending on whether the power output is essentially continuous over time or whether its output takes the form of pulses of light on one or another time scale. Of course even a laser whose output is normally continuous can be intentionally turned on and off at some rate in order to create pulses of light. Most laser diodes used in communication systems fall in that category.

In the same year, approximately 733 million diode lasers, valued at $3.20 billion, were sold. Like astrophysical masers, irradiated planetary or stellar gases may amplify light producing a natural laser. Space-based X-ray lasers pumped by a nuclear explosion have also been proposed as antimissile weapons. The wide gain spectrum of available dyes, or mixtures of dyes, allows these lasers to be highly tunable, or to produce very short-duration pulses . Although these tunable lasers are mainly known in their liquid form, researchers have also demonstrated narrow-linewidth tunable emission in dispersive oscillator configurations incorporating solid-state dye gain media. In their most prevalent form these solid state dye lasers use dye-doped polymers as laser media.
For a given pulse energy, this requires creating pulses of the shortest possible duration utilizing techniques such as Q-switching. Pulsed operation of lasers refers to any laser not classified as continuous wave, so that the optical power appears in pulses of some duration at some repetition rate. This encompasses a wide range of technologies addressing a number of different motivations. Some lasers are pulsed simply because they cannot be run in continuous mode. For continuous wave operation, it is required for the population inversion of the gain medium to be continually replenished by a steady pump source.
