laser production is done by a solid state active working material.
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
LASER is Light amplification by stimulated emission of radiation. As far as I have understood, Solid State laser is a macroscopic form of diode laser. Thus a small semiconductor diode is similar to a solid state laser except for the mechanism of lasing and size.
Rubies are hard...on the hardness scale they are next to diamonds with a hardness of 9.0...A ruby laser is a solid state laser that uses a synthetic ruby crystal as its medium. Ruby lasers produce pulses of visible light and deep red color....They are used in a number of applications where you need short pulses of red light...for making holographs...and tattoo removal
solid state laser material
None, LASER diodes are solid state semiconductor devices.
does the ruby laser treat bolld vessels

I believe that tony own you.
Not usually. Laser pointers are usually diode lasers.
Gas,solid state,diode The first laser was a solid state laser. Solid state refers to any solid material like a glass rod. Diode lasers are very common because they are used to read compact disks and digital video disks in computers, CD players, and DVD players. Before diode lasers, the most common type of laser may have been the helium-neon laser, in which the active medium is a combination of the two gasses helium and neon.
A semiconductor laser is a type of laser which utilizes a semiconductor as its Photon source, rather than a gas (Argon, CO2, Etc...) laser which uses inert gas as an active medium. Many physicists and engineers consider a semiconductor laser a type of "Solid-State" or "Two-State" LASER.
A diode laser. Also, a continuous wave laser.A diode laser. Also, a solid state laser.A diode laser. Also, a high efficiency laser, comparing to other types of laser.It's a semi-conductor laser
