What does the acronym laser mean group of answer choices?
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term “laser” originated as an acronym for “light amplification by stimulated emission of radiation”.
What does the acronym laser stands for?
Light amplification by stimulated emission of radiation
What words are represented by the acronym laser?
The word laser is an acronym for the expression “light amplification by stimulated emission of radiation.” In other words, a laser is a device capable of converting light or electrical energy into a focused, high energy beam.
What is laser and its uses?
Lasers are also used in many surgical procedures such as LASIK eye surgery. In manufacturing, lasers are used for cutting, engraving, drilling and marking a broad range of materials. There are many applications for laser technology including the following: Laser Range Finding.
What is laser and its types?
Figure 1.
| Laser | Type | Applications |
|---|---|---|
| ArF, Krf, XeCl, Xef | Gas (excimer) | UV lithography, laser surgery, LASIK, laser annealing |
| Nitrogen | Gas | Dye laser pumping, measuring air pollution |
| Dye | Liquid | Spectroscopy, laser medicine |
| GaN | Semiconductor | Optical disc (Blu-ray) reading/recording |
What is the full from of laser?
How do you classify lasers?
Lasers are classified for safety purposes based on their potential for causing injury to humans’ eyes and skin. Most laser products are required by law to have a label listing the Class. It will be listed either in Arabic numerals (1 2, 3R, 3B, 4) or in Roman numerals (I, II, IIIa, IIIb, IV).
What are the two types of laser beams?
Lasers are commonly designated by the type of lasing material employed. There are four types which are: solid state, gas, dye, and semiconductor.
What Colour laser is most powerful?
green lasers
Are Class 1 lasers eye safe?
Class 1. A Class 1 laser is safe under all conditions of normal use. This means the maximum permissible exposure (MPE) cannot be exceeded when viewing a laser with the naked eye or with the aid of typical magnifying optics (e.g. telescope or microscope).
What makes lasers dangerous?
Improperly used laser devices are potentially dangerous. Effects can range from mild skin burns to irreversible injury to the skin and eye. The biological damage caused by lasers is produced through thermal, acoustical and photochemical processes.
Can Class 2 lasers damage your eyes?
A Class 2 laser is relatively weak. It normally would not harm an eye unless a person deliberately stared into the beam. Laser protective eyewear is normally not necessary. A Class 2 laser is not a skin or materials burn hazard.
