Invented by Maiman in 1960; this fantastic beam of light has emerged as very useful beam of energy for carrying out a diverse set of materials processing activities like transformation hardening of steel, remelting, surface alloying, cladding and welding of metallic and composite materials and cutting of literally any material. Sophiticated activities like micromachining, thin film depostion are also carried out using high power pulsed laser systems.
The fundamental principal behind laser beam generation are "Population Inversion" and "Stimulated Emission". These mechanisms were proposed by none less than Albert Einstein himself as early as 1917.; who can be rightly termed as the enlightened mind going by the fact that all of his major works have strong connection with light.
For materials processing community a laser is nothing but an intense beam of light capable of heating, melting and evaporating literally any material. Besides, there are many tangible and intangible benefits of laser materials processing which will be discussed in subsequent blogs.
