Summary

The following materials are mediums used in laser assemblies to produce different wavelengths of light.

Colored lights, instead of colored lasers, are made from lamps with certain metal halides.

UV Light

Source: https://en.wikipedia.org/wiki/Excimer_laser

Possible materials:

Krypton Chloride
Xenon Fluoride
Xenon Chloride
Argon Fluoride
Krypton Fluoride

Visible Light Lasers

Red light

He-Ne medium
Ruby medium
Titanium-doped sapphire

Yellow light

Terbium gallium garnet medium

Blue light

Pr:YLF
Tb:YAG

Infrared

Ho:Cr:Tm:YAG (triple doped yttrium aluminum garnet)

Used widely in military and medical applications

Er:YAG

Laser medium with 2,940 nm emission

Nd:YAG

Emtis from 1000-1500 nm

Synthesis of Nd:YAG: https://patents.google.com/patent/CN101311373B/en

Nd:YVO

Emits from 914 nm to 1342 nm

Cr:YAG

Emits at 1 micrometer, good Q-switch (for making powerful lasers with short pulse)

Dysprosium-cadmium chalcogenides

Gamma ray

Annihilation of positronium would produce gamma rays, which might be used for gamma ray lasers
