Difference between he-ne laser and ruby laser?
1.he-ne laser is gaseous state. Ruby is solid state laser. 2.he-ne laser requires electrical pumping. ruby laser requires optical pumping. 3.he-ne laser has 4 energy levels. ruby has 3 energy level. 4.he-ne laser gives continuous output. ruby laser gives output in form of pulse 5. he-ne laser is cheaper
What is the Ruby laser wavelength?
A ruby laser is a red laser with a wavelength between 694 nm and 628 nm. 1 nanometer = 1×10−9 meter.
Why is a ruby laser used as a cooling agent?

How is he-ne laser superior to ruby laser?
Helium neon laser is better than ruby laser or most of the four level lasers are better than three level lasers due to the following reasons: The laser output is continuous in the case of helium-neon laser. But it is in the form of pulse in the ruby laser. Ruby laser requires high power pumping source, whereas Helium-neon laser requires low power pumping source like electric discharge. Efficiency of helium-neon laser is more than ruby laser. The defects due to crystalline imperfections are also present in the ruby laser. But it is not so in the helium-neon laser.
Who invented Light Amplification by Stimulated Emission of Radiation?
Light Amplification by Stimulated Emission of Radiation (LASER) was invented by Theodore H. Maiman in 1960. Maiman, an American physicist, developed the first functional laser using a synthetic ruby crystal. His invention revolutionized various fields including medicine, communications, and manufacturing.
When was the laser printer invented?
the laser printer was invented in 1969 dumbasses
Why ruby laser is a solid state laser?
laser production is done by a solid state active working material.
Who are invented first laser keyboard?
IBM are invented the first laser keyboard.
Who discovered laser?
Lasers were not discovered, but rather were invented - by a man called Theodore Maiman. Maiman created the first Laser, a ruby Laser, in 1960."L.A.S.E.R." is an acronym standing for:LightAmplification byStimulatedEmission ofRadiation (Not nuclear radiation, but light or photon radiation)
What colour lights does a ruby laser produce?
red
