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 gem is commonly used when creating lasers?
The gem commonly used in laser technology is synthetic ruby, which emits red light. Ruby is a popular choice for creating solid-state laser systems due to its optical properties and ability to produce high-intensity light.
What gem is commonly used in creating laser beams?
Ruby is the gem commonly used in creating laser beams due to its ability to produce coherent light when stimulated. It is used in various types of lasers, including solid-state lasers, to generate powerful and focused laser beams for various applications such as cutting, welding, and medical procedures.
Who made laser beam first?
The first practical laser was developed by Theodore H. Maiman in 1960 at Hughes Research Laboratories. He used a synthetic ruby crystal to produce a red beam of light.
Why mirrors used in ruby and He-Ne laser?
Mirrors are used in ruby and He-Ne lasers to create an optical resonator cavity for the laser to oscillate and produce coherent light. The mirrors reflect the emitted light back and forth within the cavity, amplifying the light through stimulated emission process. This process helps to establish the necessary conditions for laser action, where the light waves are aligned and reinforced to produce a powerful coherent beam.
Why cooling is used in ruby laser?
Cooling is used in ruby lasers to maintain the optimal operating temperature of the ruby crystal, which is crucial for achieving efficient population inversion and minimizing thermal lensing effects. Excessive heat can lead to thermal distortion and degradation of the laser medium, negatively impacting beam quality and output power. By cooling the ruby, the laser can operate more effectively, ensuring stability and longevity of the system. Additionally, effective cooling helps to manage the heat generated during the lasing process, allowing for higher repetition rates and improved performance.
What type of pumping is used in ruby laser and why?
This is kirit vaghela, The answer for the above question is that as far as ruby laser is concerned the pupmping is used is nothing but it is completed by optical pupmping.
What is the purpose of the ruby laser used in technology?
The red ruby laser is used in standard DVD players to read standard DVD discs. They are now being superseded by the blue laser DVD player, otherwise known as Blue-Ray players and discs.
Why ammonia act as cooling agent?
Ammonia acts as a cooling agent because it has a high latent heat of vaporization, meaning it absorbs a significant amount of heat when it evaporates. This property allows it to extract heat from its surroundings, resulting in a cooling effect when used in refrigeration systems.

Who built the first LASER?
The first laser was built by Theodore H. Maiman in 1960 at Hughes Research Laboratories. The laser used a ruby crystal as the gain medium and produced a red laser beam.
In salon, What kind of laser they are using for hair removal?
There are actually multiple laser types used to remove hair. They are, pulsed light laser, diode laser, ND: Yag laer, alexandrite laser, and ruby laser. Here's a site that has information on each type: http://www.laserhairremovalreview.com/
Name the substance which is commonly employed as a cooling agent in the refrigerator?
The substance commonly used as a cooling agent in refrigerators is called refrigerant. One commonly used refrigerant is R-134a, which is a hydrofluorocarbon (HFC) compound.
Why is nitrogen is used as a cooling agent?
Nitrogen is used as a cooling agent in its liquid state due to its low temperature and efficient heat transfer. It is capable of keeping components at sub zero temperatures even under load.
What is the industrial purpose of water?
Water is used as solvent, cooling agent, cleaning agent, reactant, for electrolysis in many industries.
What was the material used to build the first laser?
ruby steel and glass next time please just google it.
