A simple and by no means comprehensive explaination is;
A L.A.S.E.R (Light Amplification by Stimulated Emission of Radiation) is produced by 'pumping' energy into electromagnetic radiation, often light within a crystal or gas which has a mirror at one end and a semi-permeable mirror at the other. This energy aligns the light rays and gives them all the same frequency. They are then called 'coherent'. They bounce between the mirrors until such an energy lever is acheived whereby the beam breaks out of the semi mirror in a tight powerful beam.
I believe you are referring to a laser beam.
is coherent, monochromatic, and concentrated in a narrow beam.
A laser (light amplification by stimulated emission of radiation) is a device that produces a narrow beam of coherent light by amplifying light through a process called stimulated emission. This beam of laser light can be focused to a very small spot and is used in various applications ranging from scientific research to medical procedures.
A laser is a device which produces an intense beam by stimulated emission of photons. This technology is used in repairing detached retinas, barcodes, making holograms and drilling holes in metals.
A laser beam is a narrow, focused, and intense beam of light produced by a device called a laser. Laser beams are used in various applications such as cutting, welding, medical procedures, and communication systems due to their ability to deliver high energy in a precise manner.

A laser produces a Gaussian beam because of the diffraction effect of the laser beam passing through an aperture. The electric field distribution of the beam follows a Gaussian shape due to the wave nature of light. This results in a beam that has a bell-shaped intensity profile with a narrower central peak and gradually decreasing intensity towards the edges.

How can yo u get laser beam?What is laser beam characteristics and principles?
No. Unless the LED is specifically a laser, you can not make it focus like a laser by putting it in a housing. A laser produces coherent light, which is why it acts like a beam. A normal LED is not coherent, and you can not make it so. Although you can not make a collimated incoherent light beam able to travel similar distances as a collimated laser beam, you can collimate incoherent light into a beam which would travel some distance with a small amount of divergence.

A laser produces coherent light, which means the light waves have the same frequency and are in phase with each other. This results in a focused and intense beam of light with high energy density.

You can't see a laser beam crossing a room because the laser produces a narrow, focused beam of light that is not scattered easily. The light particles in the laser beam are not interacting with the air particles in the room, so there are no particles for the light to bounce off of and become visible to the human eye.
A caution laser beam is a warning sign used to indicate the presence of a laser that may be harmful to the eyes or skin. It alerts individuals to use proper protection and avoid direct exposure to the laser beam.
One can see an invisible laser beam by using special equipment like a laser beam detector or by observing the beam's reflection off of particles in the air.
