Excimer is a term used today to describe a family of lasers with similar output characteristics, in that they all emit powerful pulses lasting nanoseconds or tens of nanoseconds, at wavelengths in or near the ultraviolet, and the lasing medium is a diatomic molecule, or dimer, in which the component atoms are bound in the excited state but not in the ground state. The gases are then subjected to electrical stimulation and high pressure resulting in the formation of an energized pseudo molecule known as excimer or exciplex (for noble gas halides). can not form compounds with other elements under normal conditions. The average output of an excimer laser is the product of the repetition rate or the number of pulses per second with pulse energy (in Joules).

The excimer laser is the most exciting development in eye care since soft contact lenses were developed. An excimer laser is short for excited dimer laser, which describes the mechanism by which the laser pulse is generated. Binding of proteins to polystyrene plates used in enzyme linked immunosorbent assays (Elisa tests) has been improved by three different methods using UV radiation from an excimer laser. Excimer laser is often combined with creams like steroids and … A laser is a device that emits a beam of coherent light through an optical amplification process. These pseudo molecules can exist only in energized states producing a laser beam of ultraviolet light. The excimer laser delivers high-energy monochromatic UVB at 308 nm. M. Popov, and V. A. Danilychev invented the excimer laser in 1970 at Lebedev Physical Institute, Moscow. While the actual process sounds rather brutal as described, the laser can be tightly controlled to target the desired area without causing residual damage. micro machining. Once the repetition rate exceeds a certain value the energy produced per pulse gets reduced. The energy dissipates quickly, limiting risks of lingering radiation. Excimer lasers are typically used in machining materials which are hard to machine with other types of lasers, or where very high precision is required. 2. WHAT IS EXCIMER LASER? This fixes the refractive error in the patient’s eye. Excimer laser in children is used in all situations when full correction is not possible to achieve by conventional ways.
