Plasma is a special form a material and is compose of a collection of charged particles. It is exposed to electromagnetic fields and gets form of quasi-gas clouds or ionized beams. So, one can distinguish it from other ordinary form of materials: solid, liquid, and gas.
Laser is based upon light amplifying through stimulation of radiation in a resonance cavity. In recent years, there has been an increasing trend in investing in high power lasers with pulsed technique and also changing frequency by the aid of higher order harmonics. In this domain, being equipped with excellent knowledge of active materials for laser, electrical or optical pumping, resonators, and cooling and heat removal is necessary. Material processing by laser beam is another noticeable domain.
