A laser beam consists of a single frequency of light, therefore it cannot form a spectrum or rainbow.
Who invented the laser disc?
The first commercial laser disc was made by the Philips company
When was the laser pen invented?

When where and how was the laser pointer invented?
The first patent of the visible laser beam machine was awarded to Gordon Gould in 1977. However, pieces of this invention have been initiated by the Einstein, who was fascinated with light beams. However, Charles Townes and Arthur Schawlow have been implementing the visible masers since 1958, without a specific patent.
Can laser light reached at moon and can reflect back?
Yes. The moon's high albedo is used as a mirror to reflect laser light from the Earth. They more accurately track the orbit and distance of the moon than previous methods. However, in order to have a reflected laser beam that the eye could see (like in a movie) the laser would have to be incredibly strong and have a large beam. No laser currently on Earth is capable of this. However, the moon's albedo is high enough that if such a significantly large laser existed it could reach the moon and be reflected back.
What does laser beam mean?
A laser is the device itself, the beam is.. well, the beam coming out of the laser.

In a laser printer the beam detect mirror detects the laser beam by reflecting it to a blank?
optical fiber
What is a laser modulator used for?
A laser modulator is used to change modulate a beam of light (or laser). The easiest way that they modulate the laser, or light beam, is by changing the rate at which the laser is emitted from the source.
Laser beam needs electricity or not?
All lasers require electricity to operate. The laser beam that results from operation of a laser is electromagnetic radidation, not electricity.
What is the shape of the path of a laser beam?
Since a laser beam is light all moving on the same direction, the path of a laser beam will be a straight line, inless it is redirected by a reflective surface.
Who Invented laser guns?

How does a laser beam garage door work?
A laser beam garage door opener works when the beam is broken by a vehicle or an opener is activated. The activator opens the door.
