LASER is an electromagnetic radiation that sends equal amounts of light in terms of frequency and waveform, merging with each other to become a high-energy, high-energy optical pulse. , And its angle is somewhat diffuse, relying on the stimulation of radiation to be generated. The laser beam angle and its high energy efficiency are of great importance as they are used in many fields, most notably measurement. They are used to produce high accuracy results in measuring small and large distances. They are also used for heat generation in industrial cutting operations. The medical field is used in surgical operations. Types of laser gas laser (Excimer LASER): Gas enters the generation of laser radiation, and classifies the gas laser to: CO2 laser. Neon Helium Laser. Argon ion laser. Dye Laser: It is also called a dye laser, a type of laser that is produced and generated in a liquid medium where organic dyes are dissolved in a solution of ethyl alcohol and is used in many fields including medical, mechanical and communication. Semiconductor laser: It has a number of names including diode laser, diode laser, depends on the generation of laser radiation on semi-conductive materials, and the most characteristic of this type of other types of laser as low energy consumption. Solid-state laser: A type of laser that relies on the steel medium to produce and generate rays. Examples of these materials or solid media such as sapphire or aluminum alloy. Chemical lasers: This type is dependent on the chemical reactions to generate and produce laser light. Argon ion laser. Infrared Laser: This type is based on infrared radiation, which looks like a spectrum with a short-range pulse. Laser Uses Laser enters the electronics industry. It is an effective tool for measuring the short and very large distance with all accuracy. It is used in the treatment of certain diseases, especially the eyes, and these diseases: retinopathy in patients with diabetes. Retinal holes disease. Ophthalmopathy (shortness or length of sight). Dispose of tumors inside. Cosmetic operations. It is used by doctors in some major surgeries such as cardiothoracic surgery, It is a cosmetic way to get rid of hair and remove it. Used in separating and cutting hard boards. Applications of laser industrial fields, and involves cutting and welding of solids and heat treatment. Medical fields, and the latest findings of medicine, where it depends on it to avoid bleeding bleeding and conduct surgeries without blood. Defense fields, most notably radar defense. Scientific fields, and involved in laser scattering, laser ablation, and spectroscopy. Commercial areas, from their uses in the field of commercial CD-ROMs, laser pointers, and barcode scanners.
