Ruby is an aluminum oxide crystal in which some of the aluminum atoms have been replaced with chromium atoms. Chromium gives ruby its characteristic red color and is responsible for the lasing behavior of the crystal. Chromium atoms Absorb green and blue Light and emit or reflect only red light. For a ruby laser, a crystal of ruby is formed into a cylinder. A fully reflecting mirror is placed on one end and a partially reflecting mirror on the other. A high-intensity lamp is spiraled around the ruby cylinder to provide a flash of white light that triggers the Laser action. The green and blue wavelengths in the flash excite electrons in the chromium atoms to a higher Energy level. Upon returning to their normal state, the electrons emit their characteristic ruby-red light. The mirrors reflect some of this light back and forth inside the ruby crystal, stimulating other excited chromium atoms to produce more red light, until the light pulse builds up to high power and drains the energy stored in the crystal. The optically pumped, solid-state laser uses sapphire as the host lattice and chromium as the active ion. The Emission takes place in the red portion of the spectrum.

Why ruby laser is a solid state laser?
laser production is done by a solid state active working material.
What was the active medium used in first working laser?
A ruby rod Theodore Maiman built the first working laser using a ruby rod while working at Hughes Research Laboratories in Malibu, California. It lased for the first time on May 16, 1960.

Who invented a laser pointer?
The laser pointer was invented by Theodore H. Maiman in 1960. Maiman was an American physicist who developed the first working laser technology using a ruby crystal.
When was the laser pen invented?
The laser pen was invented in 1960 by Theodore H. Maiman, an American physicist. He demonstrated the first working laser using a ruby crystal. The laser technology was later adapted for various applications, including the laser pen.
Is a laser pointer a ruby laser?
Not usually. Laser pointers are usually diode lasers.
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.
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 type of gems is used to make lasers?
Gems such as ruby, sapphire, and garnet are commonly used in the construction of lasers. These gems are referred to as laser crystals and are chosen for their unique optical properties that help amplify and generate laser light.
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.
Who invented ruby laser?
Theodore H. "Ted" Maiman at Hughes Research Laboratories on May 16, 1960
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)
