What Is Excimer Laser? An excimer laser is a type of ultraviolet (UV) laser, often more accurately named as an exciplex laser. It utilizes a mixture of halogen, noble gases, etc. This type of laser has the ability to fluctuate at an extremely high laser performance in the ultraviolet range. Also, this characteristic enables functionality that is comparatively lightweight. All this advanced technology is used in a number of areas such as medicine, industry, and engineering. It is performed in the operation of eye-sight correction, manufacturing of microelectronic devices, embedded chips built with semiconductors, and micromachining.
