they have same characteristic of being a light.
How atomic excitation lead to concept of laser?

laser light is produced by solar reacting pannels that are transfered into capsules that contain magna light that turn into a small red flash of light.
Light at 489 nanometers is in the blue area of the spectrum. Use the link below for more information.
An infrared pointer uses light that is mainly in the infrared spectrum, and so is mostly invisible to humans. A laser pointer in general refers to any device using a beam of light to mark an object. Both use the same basic technology. The only difference is the wave length. IR lasers are outside of the visual spectrum where as standard laser pointers are within the visual spectrum.
Technically, yes. A laser is a concentrated beam of monochromatic (usually) light. Given that light itself is considered to be part of the electromagnetic spectrum and that that spectrum is referred to as electromagnetic radiation (as it doesn't need a medium to travel through) then one could deduce that a laser beam is radiation. In addition, gamma radiation also forms part of the electromagnetic spectrum.
no
A laser beam consists of a single frequency of light, therefore it cannot form a spectrum or rainbow.
