Charles Hard Townes and Arthur Leonard Schawlow began studying the infrared laser in 1957 and focused on visible light, originally calling it an "optical maser". Bell Labs filed a patent for their proposed optical maser in 1958. Lasers have been developed using chemical reactions, excimer gases, solid materials, fiber optics, semiconductors, dyes, free electrons, nuclear reactions, and photonic crystals, and lasers are predicted to be used both as highly dangerous weapons and everyday tools.
Laser, Pumping schemes, types of lasers and applicationsPraveen Vaidya
The document gives good insite into the different pumping schemes, different types of lasers and Applications like Holographys, laser cutting and Laser Beam Welding.
This document describes 5 types of lasers: solid state lasers like ruby and neodymium-YAG lasers which have a solid lasing material, gas lasers like helium-neon which emit visible light, excimer lasers which use reactive gases to produce ultraviolet light, dye lasers which use organic dyes and are tunable, and semiconductor lasers also called diode lasers which are small electronic devices.
