Beyond considerations of size, solid-state lasers offer a host of advantages. Read this comprehensive guide to learn more about laser cutting technology. Semiconductor lasers do not belong in this category because these lasers are usually electrically pumped and involve different physical processes (see Back to Basics, April 1995, p. 65). Although the solid-state laser is considered new in metal cutting processes, the first laser demonstration in a laboratory in 1960 was a solid-state laser. G.HEMANTH{14BF1A0460} On the contrary, Solid state lasers differ in the geometry of their amplifying media: some are large (generally crystals) of millimetric dimensions and there are optic fibres that can be several metres long. These are usually damped, eventually leading back to the steady state. Bulk lasers can thus easily achieve millijoule pulse energies and megawatt peak powers. - For more information kindly visit : Bharat Book Bureau provides the report, on “ Market outlook on Global Solid-State Laser [2016-2020] ”.
