Not usually. Laser pointers are usually diode lasers.
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.
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
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.
The Ruby laser emits light at a wavelength of approximately 694.3 nanometers.
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.
laser production is done by a solid state active working material.

^The object I know of is a ruby.
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.
Lightening creams such as hydroquinone and laser or light devices such as an IPL or Ruby laser
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 They are now being superseded by the blue laser DVD player, otherwise known as Blue-Ray players and discs.
