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.
A He-Ne laser typically operates at a longer wavelength (632.8 nm) compared to a ruby laser (694.3 nm), which allows for better precision in certain applications. Additionally, He-Ne lasers have a narrower linewidth and better beam quality, making them suitable for more precise and high-resolution applications such as microscopy and interferometry.

Why does sister superior let Esperanza have lunches in the canteen?
Sister Superior allows Esperanza to have lunches in the canteen because she recognizes Esperanza's delicate nature and wants to help her feel more comfortable during lunchtime, as Esperanza is too shy to sit with the other girls. Sister Superior is compassionate and understanding of Esperanza's challenges and wants to support her in feeling included and cared for.
When is explanatory research method superior to a predictive method?
Explanatory research is superior to predictive research when the goal is to understand the underlying reasons and relationships between variables, rather than solely making predictions based on data patterns. Explanatory research helps in uncovering insights and providing a deeper understanding of the phenomenon being studied. It is especially useful when prior knowledge is limited and when the research aims to explain causality rather than focusing on forecasting future outcomes.
What term means the belief that one race is inferior to another?
The term is "racism." It refers to the belief that one race is superior or inferior to another, often leading to discrimination, prejudice, and power imbalances based on race.
What is racial idealism?
Racial idealism is the belief that certain races are inherently superior to others, based on characteristics such as intelligence, character, or physical attributes. This ideology has been used to justify discrimination, segregation, and violence against marginalized groups throughout history.
The theory that history would be understood as the struggle among races with the fittest triumphing is called what?
This theory is called social Darwinism. It applied Charles Darwin's theory of natural selection to human societies and justified imperialist and racist policies by suggesting that certain races were superior to others.
How exactly does a hene laser work?
A hene laser work using a tube filled with helium and neon gas, and two mirrors. When the gas is excited, one mirror reflects the laser completely, while one lets a smaller percent of the desired wavelength pass through which emits the laser.
Does a ruby laser treat blood vessels?
does the ruby laser treat bolld vessels
Is a laser pointer a ruby laser?
Not usually. Laser pointers are usually diode lasers.
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
Who invented ruby laser?
The ruby laser was invented by physicist Theodore H. Maiman in 1960. He constructed the first successful laser using a synthetic ruby crystal to produce red laser light.
What is the Ruby laser wavelength?
The Ruby laser emits light at a wavelength of approximately 694.3 nanometers.
What Has the superior quality of printing?
A laser printer.
Why is a ruby laser used as a cooling agent?
A ruby laser is not used as a cooling agent. Ruby lasers are actually used for producing laser light by stimulating the ruby crystal to emit photons. Cooling agents are typically substances used to lower the temperature of a system, such as refrigerants or coolants.
Why ruby laser is a solid state laser?
laser production is done by a solid state active working material.
Is hene a word?
"Hene" is not a standard English word. It may be a misspelling or a word in a different language.
What has the author Derek Hellmut Hene written?
Derek Hellmut Hene has written: 'The British Health Service'
What colour lights does a ruby laser produce?
red
