Laser
I believe you are referring to a laser beam.
Yes, it is made out of light. LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. Laser light is coherent--the waves are all aligned, and the beams are generally tightly collimated, with very little attenuation of the beam over great distances.
It is called a beam.
A non-divergent beam from a laser.
Laser
it is highly monochromatic
I believe you are referring to a laser beam.
i think its just a concentrated beam of light
Because a laser is just concentrated light, so it is thin from being concentrated.

Lasers are highly concentrated beams of light. The more concentrated the beam, the hotter the beam becomes on contact with the metal. From here, there are several different methods that can be used. The one you probably have in mind would be reactive cutting, which is usually used for carbon steel that is over 1mm.
Light beams are photon particles that can be radiated/emitted in a beam, or concentrated in a stream (also known as a LASER - Light amplification by stimulated emission of radiation.)
It is called a beam.
Yes, you can. Just take a magnifiying glass and focus the beam until you see a concentrated beam of light towards the thing you desire to light on fire.
A non-divergent beam from a laser.
Yes, this is called the photoelectric effect. Discovered my Einstein.
