The argon fluoride (ArF) laser is an excimer laser that consists of a mixture of noble gas such as xenon, krypton or argon and a halogen gas such as chlorine or fluorine, which when subjected to high pressure and electrical stimulation emits stimulated ultraviolet (UV) light in the range of 193 nm.
Carbon monoxide (CO) laser offers high average power in repeated pulsed modes and an effective control of pulse duration and output energy.
In a chemical oxygen-iodine laser, a basic hydrogen peroxide solution acting as an energy source is rather bulky to carry in the mobile body. In addition, the solution cannot be stored for a long time as it tends to decompose.
Helium selenium laser falls into the category of metal-vapour lasers. The operation mode of this laser is similar to that of the helium cadmium laser. Spontaneous emission occurs when selenium switches between its excited states.
Ford have designed this system to generate a 3D model of a vehicle's paint status by gathering 3,000 images in the space of 15 minutes to track tiny dirty particles smaller than a grain of salt.

Pyrromethenes belong to the family of highly efficient laser dyes that exhibits effective laser action and effective laser action owing to their weak triplet-triplet absorption and planar structure.
Neodymium-doped yttrium lithium fluoride is the most common lasing medium for diode-pumped and arc lamp-pumped solid-state lasers.
