The word LASER stands for Light Amplification by Stimulated Emission of Radiation .
What does the acronym laser mean quizlet?
What does the acronym LASER stand for? light amplification by stimulated emission of radiation . Define amplification: Pushing electrons to a higher energy level.
What does the acronym laser mean?
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 Short answer?
Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths.
What does the word laser stand for answers com?
The word laser is actually an acronym which stands for “ Light Amplification by Stimulated Emission of Radiation “. The first laser was constructed by Theodore H. Maiman in 1960.
What is laser and its application?
Laser is an optical device that generates intense beam of coherent monochromatic light by stimulated emission of radiation . ... Because of these unique properties, lasers are used in various applications. The most significant applications of lasers include: Lasers in medicine. Lasers in communications.
What does the acronym pin stand for?
Someone's PIN or PIN number is a secret number that they can use, for example, with a bank card to withdraw money from a cash machine or ATM. PIN is an abbreviation for ‘ personal identification number .
What are three properties of laser?
Properties of laser light are: monochromacity (the same color), coherence (all of the light waves are in phase both spatially and temporally), collimation (all rays are parallel to each other and do not diverge significantly even over long distances).
What is the word laser an acronym for Milady?
What does the acronym laser stAnd for? Light . Amplification . Stimulation .
What does the acronym laser stAnd for what characteristics of a laser makes it suitable for today's experiment?
What characteristic of a laser makes it suitable for today's experiment? LASER stands for: Light Amplification by Stimulated Emission of Radiation . The characteristics are: Coherence, directionality, monochromatic, and high intensity.
What is laser and its types?
Lasers are often described by the kind of lasing medium they use – solid state, gas, excimer, dye, or semiconductor . Solid state lasers have lasing material distributed in a solid matrix, e.g., the ruby or neodymium-YAG (yttrium aluminum garnet) lasers. The neodymium-YAG laser emits infrared light at 1.064 micrometers.
What are the four properties of laser?
While not exhaustive, the most common laser output characteristics include: wavelength, gain bandwidth, monochromaticity, spatial and temporal profiles, collimation, output power, coherence and polarization .
What is the importance of laser?
Laser technology is very important in the modern world because it is used in many fields, most notably measurement, where it is used to give high accuracy results in measuring small and large distances . Laser technology is also used for the purposes of generating heat in industrial cutting processes.
What is laser principle?
The principle of laser amplification is stimulated emission . ... As high laser powers saturate the gain by extracting energy from the gain medium, the laser power will in the steady state reach a level so that the saturated gain just equals the resonator losses (→ gain clamping).
What is the full form of laser and radar?
LASER- Light Amplication by Stimulated Emission of Radiation. RADAR-Radio Detection And Ranging .
Which laser is eye safe?
Lasers with emission wavelengths longer than ≈ 1.4 μm are often called “eye-safe”, because light in that wavelength range is strongly absorbed in the eye's cornea and lens and therefore cannot reach the significantly more sensitive retina.
