Detailed Solution:

The correct answer is “stimulated radiation”.

Laser is a device for producing stimulated radiation.

In a laser, atoms are excited to a higher energy state. When these excited atoms interact with incoming light of a specific wavelength, they are stimulated to emit light of the same wavelength and phase. This process is known as stimulated emission, and it results in a coherent, intense beam of light.
