Can we amplify light from various sources say light from a bulb?
Technically no. Light is energy, and you cant create or destroy energy. You can magnify it which can give the effect of amplifying.
Yes, that is where we get lasers. I think Laser is actually an acronym for Light Amplified by the Stimulation and Emission of Radiation.
from certain sources, yes. A LASER stands for (Light Amplification through Stimulated Electromagnetic Radiation). By using the proper reflective systems and the right gasses combined with the right frequency light, the energy is amplified to form the laser
